You point out two aspects which confuse noob me. I associate crashes with bubbles. Because economies are complex adaptive systems (butterfly effect), crashes are inevitable. Knowing this, policy makers do what they can to minimize bubbles, soften crashes. For which their is tremendous pushback (no good dead goes unpunished). Some of the kibitzing wrt MMT is the distinction between inflation and interest rates. I gather that the anti-Keynesian rhetoric has traditionally focused on inflation (and deficits), and the MMT advocates are arguing that model is too narrow. I have no idea what all that means.
