Currently no society has pure socialism or pure capitalism. There is a mix. The question is, how much of each.
That said, Sweden treated it's banks a lot more capitalistic than we have. And Norway has a lot of millionaires per capita. Go figure
I'm not saying they have the greatest system, but painting with broad strokes is a bit simplistic. As I said, all countries have a mix of the two.
Our Socialism really benefits the top percent. And it's not a recent phenomena. I think it's funny to see my fellow countrymen complain the loudest when it's the lower class schleps that get nickles, and when the 100 dollar bills go to the plutocrats, less is said.
By the way, I studied tax law in Law School, you will be shocked by the many loopholes specifically created for wealthy types - actors, hedge fund managers, ballplayers, etc.... If you factor in all these loopholes, over the past 30 years our tax code has flattened, it has become less progressive from the days that the top rate was over 70%.
Gee, were we starved, unentrepeneurial commies form the 1950s-1960s when the rates were that high?
I'm no fan of higher taxes. But let's not boil this discussion down to simplistic unrealistic scenarios. There's a reason that over the last 30 years wealth has accumulated into fewer hands. And Socialism ain't the reason. At least not the traditional sense of Socialism.
