The US is currently the most powerful country in the world, true, the US got its problem and isn't perfect, but it is doing really well. As for those religion nuts that is angry at the US moving further away from Christianity, that is actually on the right path, as for those who say US is founded on Christian value, any historians would tell u that isn't the case, the US, is founded in respect to Christian value, in fact most of the US founding father, qualify for the bible definition of a Satanists. A real satanists according to the bible and our pop culture image of a satanists is very different, according to the bible a satanists, is anybody who contradict, not subject to or refuse to follow the Christian god, which the bible accuse of been liars, evil and demonic. example of satanic institutions/priests include eg public school, Buddhism, evolution, Charles Darwin.
As a white person that grew up in Asia, I frequently compare to modern US' success to why ancient Asia was so powerful. Unlike traditional west that make us vs them distiniguish base on racial, culture, heritage, religion or ethnic difference, ancient Asia make no such differentiation, their only differentiation is between good and bad people and they believe u do nothing bad as long as u don't effect the freedom of others, this is same as modern US value, thus, people won't be busy fighting stupid war such as race war or religion war and make national unity easier and allow using competent people from any background, including migrants. They believe strongly in nationalism, same as modern US. They had 3 level self governing system, federal, state, city and town, same as modern US, only difference is, the US one is democratic(which is better), ancient Asia one it is a Prefect appointed by the Emperor, holding all power. They believe in the right of religion freedom, as long as such religion doesn't threaten society or cause harm to others, but if violated such principle the religion is a cult thus can be suppressed, just like modern US. After, taking power in the 1950s, the Communist work hard to suppress these values, due to its threat to the Communist party, fearing Chinese ally with US to overthrow Communist and promote Communist ideology of racial, ethnic and culture base us vs them differentiation, it do result in some ethnic tension in modern China, with those who believe in modern Chinese value (Chinese Communist Party value), but Chinese conservatives, still reject these values.
