  Social paraistism and social idealism
Social parasitism persistent in modern economically developed nations is harmful not only for them, but is even more harmful for developing societies.
Social parasitism at certain point in time is becoming very difficult to reverse.
Social parasitism and social idealism are not only constantly and gradually undermining personal freedom, but are also discrediting democracy and posing a serious threat for political freedom.

  Parasitism - Wikipedia, the free encyclopedia
Parasitism can be considered a special case of predation since their effects on the host are similarly, though not equivalently, detrimental.
Parasites that live inside the body of the host are called endoparasites (e.g., hookworms that live in the host gut) and those that live on the outside are called ectoparasites (e.g., mosquitos).
Many parasites, particularly microorganisms, evolve adaptations to a particular host species; in such specific interactions the two species generally coevolve into a relatively stable relationship that does not kill the host quickly or at all (since this would be detrimental for the parasite as well; but see parasitoid).

 Parasitism [Definition]   (Site not responding. Last check: 2007-11-02)
Parasitism is a type of symbiosis, by one definition, although another definition of symbiosis excludes parasitism, since it requires that the host benefit from the interaction as well as the parasite....
Parasitism can be considered a special case of predation Predation is an interaction between organisms (animals) in which one organism captures and feeds upon another called the prey.
A parasite that kills its host is called a parasitoid Parasitoids differ from parasites in their relationship with the host.

 Theoretical Primatology Project: Research Page 2
While, in my opinion, Clutton-Brock underestimates the role of (social) parasitism (e.g., phenotypic manipulation), he provides numerous testable ideas, including his conclusion that mutualism, generalized reciprocity, and group size are variables likely to explain many cases of cooperative breeding as well as cooperation.
Relating these findings to our discussion of "social parasitism" (SP: e.g., "phenotypic manipulation"), it is important to note that SP may select for sociality in some regimes (see, for example, Crespi and Choe, 1997; Schwarz et al., 1997) and predicts exactly the sorts of discrimination capacities described for baboons by Bergman and his associates.
It is important to determine why social parasitism and other selection pressures favoring sociality (e.g., predation) have apparently led, in some taxa (e.g., many primate species, including humans) to higher-order cognition and individuality but, in other taxa (e.g., social insects) to alternate discrimination and information-processing mechanisms and to castes ("true sociality").

Social parasitism is a common and intriguing phenomenon in social insects.
Social parasitic species evolve from their social ancestors by developing mechanisms to exploit the resources of their social hosts.
Because there is reproductive isolation of the parasitic clones from the host gene pool, this sets the stage for the evolution of a queenless social parasitic honeybee Neumann and Moritz 2002) Therefore, the Cape honeybee appears to be a unique subject for studying sympatric speciation of a social parasite.

Parasitism is an interaction between two organism, in which one organism (the parasite) attains most or all the benefit of the close relationship.
Parasites that live inside the body of the host are called endoparasites and those that live on the outside are called ectoparasites.
Many parasites, particularly microorganisms, evolve adaptations to a particular host species; in such specific interactions the two species generally coevolve into a relatively stable relationship that doesn't kill the host quickly (since this would be detrimental for the parasite as well).

Brown-headed cowbird parasitism on golden-winged and blue-winged warblers.
A study of the social behavior of cowbirds from 1974 to 1975 suggests that in prairie communities the predominant mating behavior is promiscuous.
Yellow warblers were subjected to taxidermic mounts of a brood parasite (brown-headed cowbird), avian nest predator (grackle), and control (sparrow) during their egg laying and nestling stages in an effort to determine whether warblers were able to distinguish between the threats of brood parasitism and predation.

Avian brood parasitism spurred my interest in evolutionary biology as a student and parasitic birds have continued to be the focus of much of my research to date.
Indigobirds are species-specific brood parasites of a number of estrildid finch hosts and have evolved nestling mouth markings that mimic those of the host.
Parasitic nestlings also learn host songs and adult male parasites incorporate these songs into their courtship displays, resulting in assortative mating among parasites reared by the same host species.

Some parasites are social parasites, taking advantage of interactions between members of a social host species such as ant s or termite s to their detriment.
Thus, if an organism becomes physically stronger as a result of infection but loses reproductive capabilities (as results from some flatworm infections of snail s, that organism is harmed in an evolutionary sense and is thus parasitized.
Plant s often produce toxin s, for example, which deter both parasitic fungi and bacteria as well as herbivore s.

 Individual and Society:
Here the social obligation to work in the name of eliminating Donselaarian exploitation and abuse of rights has not only harms Hippie who is guilty of neither, but it has also harms Crazy, the person who it was supposed to help.
Of course, Society might give Individual nonmarket goods as well, such as social interaction, but if we are not allowing Individual to claim social interaction as his contribution to Society (Widerquist 2001b), it is rather inconsistent to allow Society to appeal to social interaction as their contribution to Individual.
People with such preferences cannot enjoy them in a society with a social obligation to work in a given economic system unless they first work for society for many years even to earn enough to purchase their per capita share of the land natural resources they would need.

Worst of all were seen to be the parasitic Untermensch ( Subhumans), mainly Jews, but also Gypsies, homosexuals, the disabled and so called anti-socials, all of whom were considered lebensunwertes Leben ( Life-unworthy life) owing to their perceived deficiency and inferiority.
The ideological roots which became German "National Socialism" were based on numerous sources in European history, drawing especially from Romantic 19th Century idealism, and from a biological misreading of Friedrich Nietzsche 's thoughts on "breeding upwards" toward the goal of an Übermensch ( Superhuman).
Many historians, such as Ian Kershaw and Joachim Fest, argue that Hitler's Nazis were one of numerous nationalist and increasingly fascistic groups that existed in Germany and contended for leadership of the anti-Communist movement and, eventually, of the German state.

 Social life-history response to individual immune challenge of workers of Bombus terrestris   (Site not responding. Last check: 2007-11-02)
In the case of social insects, where brood care and reproductive effort are shared between the queen and her workers, adjustments of the reproductive effort would depend on collective decision-making.
This induction resulted, in combination with environmental conditions, in a reduction of fitness of the social unity and a collective response towards earlier reproduction.
As both phenomena are expressed at the level of the colony, the result suggests that key elements of the use of immune defence have been maintained through the evolutionary transition to sociality.

Imagine what a new economy would be like, in which all the parasitic factors interposed by the regime of private property were suppressed, in which the producers themselves would be entitled to the benefits (plus those categories of consumers which have a natural right to existence, that is, the child, the aged and the sick).
If socialism and its variations would have conceded from the very beginning the necessity of substituting the outworn political and economic capitalism, by adequate organisms of practical economy, our conditions in the world today would be quite other than they are.
If, in the social revolution, in spite of all the obstacles, we were to become a majority, the practical work of economic reconstruction would be enormously facilitated, because we could immediately count on the good will and support of the great masses.

 EVOLUTIONARY BIOLOGY: ON SOCIAL PARASITISM
2) Thus, among insects as diverse as butterflies, crickets, beetles and flies are specialist "social parasites", perhaps 10,000 species in all, equipped to penetrate the highly protected chambers inside ant nests and feed, isolated from enemies, on the rich resources concentrated there.
The downside is that social acceptance is won only through secreting chemicals that so closely match the recognition codes of one host species that survival with any other ant is unlikely.
It is present in the oral secretions of the caterpillar, and it induces the damaged corn seedlings to release a volatile blend of terpenoids and indole, which calls in the parasitic female wasps that are the natural enemies of the caterpillars.
