At the end of the day I think it is obvious that we should be upset over Chinese financial domination, and unless we do something to stop them, they are going to won all the companies and business' all over the world eventually, not right away of course but in a few decades it will be mainly Chinese owned by the looks of it.
There is no truth in these claims. The total market capitalization of NYSE + NASDAQ is around $45 trillion. The vast majority of this amount is owned by individuals and corporations that are based in the United States. Foreign investors (especially those from China, Japan, Middle-east.etc) own only a small fraction of this amount. I don't see anything wrong with it. More foreign investment will create more demand for the stocks, and this will push up the stock prices. US citizens will benefit out of this, in the form of higher returns to their stocks. And the government will also receive higher amount of taxes.
