Let's be honest: the only reason people in the US are scared of "socialism" is the fact that they've been immersed inanti-socialism propaganda throughout all their life.
Meanwhile, you can pretty much look at any European country to see how millions of people really feel about socialism.
Unless you confuse capitalism with an extremist Ann Rayndian neoliberal framework, and in that sense you can pretty much look at countries such as the Netherlands.
Capitalism is an economic system based on private property on the means of production, and collection of economic rents on the basis of ownership. All European countries have that. The fact that they also tax those rents and redistribute that wealth into welfare makes it welfare capitalism, not socialism.
