I agree, but I think the size of public/private debt is a guarantee that rates will stay historically low for the foreseeable future.
It’s only a bomb if rates go up.
Probably best to not let Wall Street gamble with boomer retirement money on when the debt bomb will blow up. Putting Glass-Steagall rules on investment vs. commercial banking back in place would probably make sense around now.
It would have made sense to never remove them in the first place.
