Lies in your OP.
An American citizenship is NOT the most coveted thing in the world. Not even close. You're begging white people to emigrate to the USA, and you're not getting any takers. American citizenship is already "devalued" in the first world because guns, political instability and lack of affordable health care.
Your nation was built by enslaved third worlders, Mexicans, and poor white people from Europe. Rich people didn't "escape to America". People who are doing well where theey are aren't giving up wealth and power to go to a new frontier. The people immigrating to a new country are those who aren't doing well where they are. Europe's poorest most downtrodden people came to the USA.
The Irish came during the Potato Famine. The British emptied their prisons to populate Australia. Dire poverty in drove Italians to go to America. Stratified class structures throughout Europe left no opportunities for social mobility. Few of the people who actually built your country were rich or white.
It takes a lot more work, dedication and ingenuity to get OUT of a Third World country today, than it takes to be born stupid and white in the USA, like you.
The American Dream no longer exists. The Republican Party's economic policies of enriching the wealthy at the expense of the middle class, has made the American Dream beyong the reach of 80% of the population.
