I hear this a lot. In all these conspiracy and economic videos people say that this can't go on forever. At the first glance it seems obvious that parabolic rise can't go on forever but can anyone explain me why this is the case with US debt ceiling? These are just numbers in databases so why can't they be increased forever. Is US facing integer overflow with its debt ceiling?
Second question related somewhat to the first one. Let's say global politics is a competition. What if I loan a lot of money from other countries and never plan to pay back? I can then spend the loaned money on my military equipment so that if others start to demand the money to be paid back I could just show them the middle finger in the politically correct way.
