Regarding the issue of US Treasury bonds, this is actually not a problem at all, but rather a problem that has been hyped up. US Treasury bonds remain the best asset globally. It's not the amount of debt that causes problems; for example, Evergrande owes over a trillion, which leads to default and bankruptcy, while Apple owes a trillion, which has little impact. Although US Treasury debt is enormous, just look at the market values of companies like Apple, Microsoft, and Amazon. If you are worried about the risks of US Treasury bonds, you might as well worry about city investment bonds, many of which have already defaulted.
