In what ways are they socialist? For instance take a look at Germany.
Economic freedom (heritage): 77.8 (US) ... 71.8 (Germany)
Economic freedom(fraser) : 8.0 (US) ... 7.5 (Germany)
Government spending: 42.46 (US) ... 47.00 (Germany)
And just for the comparison, governmental spending in Switzerland is 34.17% and 17% in Singapore in 2010. Also, economic freedom in Switzerland is 81.9 (heritage) and 8.1 (fraser)
Why do people think Scandinavia or any of the European countries are socialists? They are not, regulations are low, there is huge support for free trade. Private people, not the government own the means of production, charter schools are normal. It is easy to open up a business, and taxes are just marginally higher than the US. However, if you take into account the upcoming mandatory private insurance in the US, taxes are about the same.
If Germany is socialist, so is America.
