Here is the issue. I can get behind your nationalism debate. Of course our friends are like minded people. Thats who we associate with. And there is nothing wrong with pride in your heritage and country as long as you dont hate the others just to hate.

But any system that requires larger government is bad. Milton Friedman described the 3 types of spending...

We spend our own money on ourself
We spend someone elses money on ourself
We spend someone elses money on others

The last is what the government does. Therefore they are not concerned with price or quality because it isnt their money or their product. The best is the smallest form of government where we spend our own money on our own services and products. Therefore we shop for best service at cheapest price. That's where capitalism thrives.
