| > Then you solve it by printing more money. the money isn't printed. It's debt, which is different. The debt is expected to be repaid, with interest. If you actually printed money, which does not have interest to be repaid, then the amount of circulating money would've increased permanently. Therefore, the expectation is that each printed dollar is worth less. By borrowing instead of printing, you don't have this permanent increase in money supply. Of course, there are other ways to increase the money supply, which is to control how much debt actually makes it into the system - but this can be regulated as required by the economy. > Other countries don't have a reserve currency like the dollar. the dollar being reserve is not really "forced" upon other countries - it's a choice they made to use USD as their reserve. They do it because other parties trust it. They could use the japanese Yen, or even the chinese yuan. And yet, majority of entities choose to use the USD. They do it because it's a relatively stable currency. They do it because other people accept it, and they do it because there's some trust that the US won't print money like Venezuela or Zimbabwe. |
You have to get your head around the fact that this is an open-ended system, the music never has to stop so long as the sun rises and we stay on this monetary system. The same way people still get "wealthier" from stock market appreciation, even though there is a buyer for each seller, so too does more debt indeed mean a permanent increase in money supply[1].
