US national debt is something i don't understand no matter how i think about it.
First, while it's debt, i can't see it in the same sense as i see *my* debt. If i default on my mortgage, my house will be taken away. Bad thing. If US defaults on its loans,
What happens?
China (or any other nation with enough of our debt) dumps the dollar en masse, the economy tanks, and we're all boiling shoes - or each other - to eat.
Why would China want to do that? It'll lose a valuable trading partner & the money it is owed, plus risk what's politely called "armed conflict"? They crazy?
Edit: If you have bought into a pyramid scheme, and you're guided by greed alone (euphemism: "invisible hand"), would you yell "scam" & out the perpetrator, or keep quiet for a chance to get out with your $$$?
China's US debt holdings have been growing year by year ( with a few small dips). (

Using your analogy ("keep quiet for a chance to get out with your $$$") , how would they do that?
By simply doing what they're doing now? Again, I see no advantages for China in destabilizing US economy. If there are some obvious ones I'm missing, please point them out.
If they stop buying debt and start selling it(even slowly) that in itself could trigger a domino effect. At some point in time somebody ( doesn't have to be china) will be willing to admit that repayment is impossible and will do it anyway to try to get back something.
China trying to dump US debt or claiming repayment impossible is no different than crying foul; see my response above. If there are scenarios where dumping US debt is in China's best interest, point them out.
How is that an answer ?- If they continue to buy more debt than the get repaid ( older debt) then they basically aren't getting paid back. Currently it isn't in their best interest apparently so the game continues. BUT... there are scenarios ( some wild) that might change their mind.
1) "War".- The world is a crazy place. So many unimaginable things have happened in the last 100 years. A world war could happen ( although slim ) that put china and the US on opposite sides.
2) "Collapse in sight "- Economic situation of the US turns towards critical. Payback of debt seems close to impossible and the US import market ( main reason for them to hold back) turns sour.
3) "Hot Potato"- They get wind that some other big debt holder could be thinking of the same thing and want to try to get out before they are last with the hot potato
4) "Insanity" - again a slim chance in this global economy but a crazy leader could do it just because.
I thought i made it clear that i was addressing only rational possibilities for China. So I'll make that clear now. Considering irrational scenarios like your #4 (Insanity) is pointless. If we concede the guy with his finger on the trigger is not governed by reason & self-interest, why muddy the waters with irrelevancies like US debt?
This also applies to your #1 (war). Sure, wars happen. Though I'm not sure how national debt plays into them.
Stick with me here, this is both funny & important:In WW2, picture an imaginary land next to Poland uncreatively named Poland2. Poland2 is identical to Poland in all respects but one: It's in debt to Germany up to its eyeballs! And the history's following the same path, with one notable difference: Germany has to choose who to attack first: Poland or Poland2? (Hint: Poland2 is making payments on its debt to Germany, which pays for gas, food & out-of-pocket expenses of the blitzkrieg.)
So war=craziness, just like #4. Forget it. If national debt factors into it, it's safer to have a whopping big one.
#2. (US economic collapse). How would US debt to china affect China's position (unless WAR, in which case go to #1)?
#3 (dumping US debt): Already addressed. See my previous replies.
TL;DR: If China is irrational and chooses war, it's in USA's best interest to max out their credit with China. If we ignore craziness, it's still better to owe than to pay -- international bonds of cooperation & friendship
