Your country is one of (if not the most) powerfull country in the world, then why do you have this problems? why don't you have universal health care? Why is it so expensive to go to college? it doesn't make any sense!
if we had universal health care...America wouldn't be as rich and powerful. a lot of money spent on wars and foreign affairs. a lot of money spent to protect the power of the top 1%
Realize the "America the Great" is not exactly "America the Reality". Many people are poor or middle class...and the middle class is dropping quickly.
Furthermore, those countries that are skinnier and healthier are slowly losing it as American fast food culture slowly creeps in to those areas. It took America at least 50 years to get where it is now (talking about the obesity epidemic) and it will take the other countries time too.
America wasn't built to walk around; it was meant to be driven. the city built for walking (New York City) is one of the fittest cities. And if you subtract all those people who are new to the city (the turnover rate is high), it would probably top the list of fittest cities.
you bring up Poland, but have you ever compared the city planning of POlish cities, cities built a thousand years ago (meaning compact and easily bikeable and walkable) to American cities and the suburbs that surround them.
Poland, with a population of 40 million has 2 million farmers. so their GDP creates a fit environment. America doesn't have that. We drive to the office or whatever place of employment. All this is changing in Poland, as their economy changes.
So finally, what i say to you is you have no idea...which is fine to voice what you think you know about America, but don't come on here saying we are stupid and you are oh so smart when that is not the case at all.
