What I hear is Keynesian ideology. Granted I didn’t listen to everything but I did watch the first video. Keynesian Economics support credit and leverage and the Austrian Economics support equity or productivity back 1:1 ratio or debt backed by real savings. What I don’t heart from MMT is defaults happen and will happen. For example, Argentina has defaulted three times in the past 30years and this is a G20 country. 10 years ago, the US fell from a AAA rating to a AA, and technically Canada has better credit rating than us. But that doesn’t matter because the US Credit Default Swap is trading much lower the Canada’s due to the US being the world’s lender. All I see is the US doing (same as every other G20 country) is open up a credit card, run up the balance, and then open up a new card credit with a higher interest rate plus lower rating to pay back previous loan.
