Is it not just as black and white as the whole "socialism/communism is bad" stuff we're fed? People act like Medicare For All would be catastrophically expensive, when even our arguably closest allies in the UK — not exactly a socialist haven! — have the NHS, which seems to work out great. They pretend the Green New Deal would mark the end times for the US, as if the last New Deal's massive investment in infrastructure didn't help revitalize the economy. But yes, I agree — the idea that best thing to do is dogmatically implement one particular economic system is absurd.
