Certainly socialism is a heavy and dangerous solution to most problems, the critiques of it are many, and of the many most are fair.
I say boogeyman not to imply it is without problems but rather to say that in the problem spaces that it is often deplored the incumbent alternative is often categorically worse for all those who do not directly benefit from it, which is usually a supermajority at a minimum. Thus, to make the incumbent more tolerable a caricature of an idea is brought forth to scare those who would otherwise support an aspirational idealist into backing the known “lesser” evils.
