USA will be a super weight in this world until

it is not. Those who are in doubt with US's future are laughing at others who believe in USA. I felt that guys in doubt relies more on assumption, imagination, guesswork. In reality, talents and capital are still coming to USA. Yep, now USA is messy, at least it is fair and transparent, that is why people and capital are coming. A simple example, if corruption is norm in USA, immigration would be a nightmare for most of Chinese, then much less Chinese would end up here. yes, immigration is tedious, time consuming, bureaucratic, but mostly it is fair, so most of people are just patiently waiting.
