It's America-centrism to think that all welfare and modernism is brought to the world by the USA. One typical anecdote a former exchange student told me, that some high school kids in the USA believed (this was at the end of the nineties) that European countries do not have their own radio channels ;). Go educate yourself, the average Western-European citizen has more luxury, more free time, and better health-care than the average citizen of the United States (I know, I have visited the US often).
The primary advantage of the US is that it is far easier to set up a company, and make it really big. If you make it, you will be rich and wealthy. If you fail, you will hit rock bottom. It is a consequence of the system, wages, taxing, etc.
