Try getting a loan from anyone after you’ve defaulted. Good luck!! If you can service the debt, you should do it if you want to keep on going. Hyper inflation that you site is far more rare and done by countries that have already defaulted. Hyper inflation comes after a defacto default….i.e..you cant make the payments without a huge increase in money and no one will lend you any.
As bad as the US is, it’s far away from that position.
There is also a lot of comparable activity going on in most every OECD country.
