This has nothing to do with socialism. Since it is a problem under capitalism why don't we call it "capitalist". Or maybe we could just say lazy.
I cannot see how that would be a vice of capitalism since capitalism is basically non-intervention and freedom.
I don't think socialism is the word you're looking for. If you're trying to say that the described behaviour ("it's everyone else's job") is common in, or a byproduct of, a socialist system then it would make more sense (though it could be argued).
But that doesn't make it a correct "approximation" of socialism. Socialism is:
>a political and economic theory of social organization which advocates that the means of production, distribution, and exchange should be owned or regulated by the community as a whole.
I did not mean anywhere every socialist is like that or that all peopple that do that are socialist.
On top of that, that is just a personal opinion. Nothing else.
