First thing would to teach people what Capitalism, Socialism, Democratic Socialism and Social Democracy is...
US is either a Social Democracy or Regulated Capitalist country and has been that way since almost its inception...
The idiots who shout Communism or Marxism are that idiots, they are just showing their ignorance on the subject... Rem: Don't argue with idiots
So really US is on a sliding scale between centre and centre right politics (with the odd Left and Right policy thrown in)...
Anyone suggesting to go too far to on side or the other should be ignored as pretty much an idiot, it has been well proven to be a disaster.
So where is US... Very much Center Right to Right in a global comparison, as example Obamacare would a centre right policy.
The powerhouse countries in EU like Germany have laws more to the left and the country seems to metrics which are preforming better than US, especially in the last 20 years (lower poverty, less income inequality, lower taxes for most of the population, better education/Healthcare...).
This doesn't mean Left wing policy is the only way but it does mean the guy calling Obamacare and Communist should be dutifully ignored...Germany has a far more comprehensive system and they ran 9 of the last 12 years with a surplus...
