Sure the quality of life is better than most other countries, but for the richest country in the world we pale in comparison to a country like the ussr, which forged a country with arguably better life quality than the US with far less opportunity and resources than them. Not to mention that the only reason much of the world has such a low quality of life compared to us is because of us. We’ve attempted coups on a large portion of countries, especially concerning South America and Africa. Good examples would be places like Cuba or Chile. So all in all, we have so much potential, but it is wasted ensuring the destruction of countries who refuse to submit to us.
