Why do U.S. stocks keep rising?

Wealthy people in the United States buy U.S. stocks
Wealthy people in China buy A-shares and U.S. stocks
Wealthy people in Japan buy Japanese stocks and U.S. stocks
Wealthy people in South Korea buy Korean stocks and U.S. stocks
…………
The people who are best at making money in the world all allocate their assets to U.S. stocks
As long as there are still countries that print money
As long as the U.S. dollar remains the global currency
Then people with money will keep buying U.S. stocks
