One thing that has changed for the worse since the 70s is our ability to (meaningfully) raise interest rates to curb inflation. I know the Fed is starting to take small nibbles at it but the impact on federal debt payments for every hike is so huge I don't think they will be able to go very far. We borrowed trillions and trillions based on the expectations of forever-zero rates -not sure we can really absorb the ballooning payments that come with even 5-10% interest rates much less the 18-20% we saw back then.
