Regarding inflation:
Ray Dalio has a bit in his latest book Changing World Order where he points out what nations/empires in the past have done when faced with similar situations that the US now finds itself in. When debt is high, and country fundamentals are decreasing (like internal stability, and global share of economic output) countries can either buckle down and take the austerity measures required to increase output + decrease the debt… or they can print more money to pay off the debt which leads to inflation. They almost always choose to print money.
