I submit that I know how and where to spend my hard earned cash better than government agent 32N and can do it in a manner that might actually stimulate both the US economy and that of the rest of the worlds.
I submit that you don't, because you know nothing about running a country. Does the government fuck up? Yes, of course it does, it's staffed by people exactly as human as you are. Think about that for a minute. But there's a Hell of a lot more to it than just stealing money and setting it on fire.
Just so you know, income taxes are right now about the lowest they've been for everybody since the income tax was instated. Back during the red-blooded 1950s under Commie fighter Eisenhower the top income bracket was taxed at something around 90% when you worked it all out. I'd have to look that up again though.
As for China holding debt, you have absolutely no understanding of China's motives if you think they're poised to annex Korea. They don't want to annex Korea, especially North Korea, because they've got enough dirt poor starving people already. And because North Korea's continued existence is a useful political wedge (for some reason). And because any notion of rearranging Westphalian national borders is something that would start a nuclear war. Now Taiwan, that's another matter.
