Letting the government set the cost of products always backfires
Leftists are silly people. Silly people do dangerous and often stupid things. Pretty much why we can't have nice things. Leftists are also unmoored from reality, hence their inability to grasp why their policies and values (or lack there of) lead to bad outcomes.
I feel a lot of this is liberals and leftists denying, or just not able to comprehend, human nature.
