Think about it: the claim is made, as an example, that workers are wage slaves. They are entirely dependent upon parasitical Capitalists who more or less own them. What is the Communist solution? More of the same, with the difference that your right to change jobs, protest bad work conditions, or organize a union is blocked. Moreover, your freedom of assembly is vitiated, as are your rights to free speech, religious affiliation, gun ownership, a fair trial, privacy, governmental representation, and to vote.
For all this, you lose the actual productive capacity of Capitalism, which even when there are clear winners and losers, does a much better job of making stuff of various sorts. We have not had bread lines in the United States since FDR did his experiments in socialism–which included among other things the completely wasteful slaughter of many thousands of pigs in order to push prices up for SOME farmers.
Quite literally, in order to embrace these contradictions you have to engage in a cognitive derangement that could be considered with justice a mental illness.
