I agree.
I remember learning that failures of Socialism were central planning, seizing the means of production and eliminating markets.
And you can point to failed states to support that.
But we have people screaming "Socialism" at the idea of a 70% top marginal tax rate, expanded safety nets etc... and you can easily point to higher marginal tax rates in Americas own past within the past 70 years where the economy was strong along with European saftey nets to dispel those fears.
And you have more economists and historians speaking publicly about those things.
Yelling socialism about those things might turn into the boy who cried wolf soon.
