People aren't running from places like Canada, Sweden, Norway, Finland, Germany, New Zealand, Australia last I checked.
Hint: Those are capitalist countries with strong welfare policies. AKA: "democratic socialism". Capitalist infrastructures with tax and spend policies (until it falls from the weight and starts declining - IE: Austerity measures to cut programs when promises outstrip the money available)
Last I checked a serious conversation relies on understanding what Socialism is. Welfare states aren't Socialist countries.
Military? not socialism. Neither are police or fire departments. so "but military" doesn't carry any real point.
And those countries? still aren't socialists countries. The US not having "private military" doesn't change that.
This isn't "black and white". This is "socialism is failure based on 100+ years of historical evidence". This is logic and evidence. As I said, those are capitalist countries with strong welfare policies. This is also basic definition of socialism which isn't "the government does stuff".
