The word is "collectivism", not "collective". Since
you apparently don't know how to perform an internet
search, I'll give you a hand.

Collectivism is a political theory associated with communism.
More broadly, it is the idea that people should prioritize
the good of society over the welfare of the individual.
Collectivism .. has to do with political theories that put
the group before the individual. In a collectivist system,
power should be in the hands of the people as a whole, not
in the hands of a few powerful folks. Collectivism is the
opposite of individualism. Ideally, in a collectivist society, decisions
benefit all the people. This is a difficult idea to
put into practice, as seen in the attempted collectivist society
of Soviet communism.

Collectivism means the subjugation of the individual to a group—whether
to a race, class or state does not matter. Collectivism holds that man
must be chained to collective action and collective thought for the sake
of what is called “the common good.”
Collectivism holds that, in human affairs, the collective—society,
the community, the nation, the proletariat, the race, etc.—is the
unit of reality and the standard of value. On this view, the
individual has reality only as part of the group, and value
only insofar as he serves it.
Collectivism holds that the individual has no rights, that his
life and work belong to the group . . . and that the group may
sacrifice him at its own whim to its own interests. The only way
to implement a doctrine of that kind is by means of brute force—
and statism has always been the political corollary of collectivism.
Fascism and communism are not two opposites, but two rival gangs
fighting over the same territory . . . both are variants of statism,
based on the collectivist principle that man is the rightless slave of
the state.
Modern collectivists . . . see society as a super-organism, as some
supernatural entity apart from and superior to the sum of its individual
members.

BTW a group of crows is called a murder. Then there is a brood of
chickens, a gaggle of geese, a rookery of albatross, a bellowing of
bullfinches, a wake of buzzards, a mob of emus, a cast of falcons, a
charm of finches, a scold of jays, a watch of nightingales, a parliament
of owls, an ostentation of peacocks, an unkindness of ravens, a fling of
sandpipers, an exultation of skylarks, a host of sparrows, a muster of
storks, a flight of swallows, a mutation of thrush, a descent of
woodpeckers, a herd of wrens. Not a collective in the lot.
