the more money is printed, or credit is issued, the more likely that bad bets will be made because of the lower opportunity cost. that's what we see with bullcrap like the current AI boom. keynesian economics incentivises just moving money around to make business look bigger than it actually is. usually somewhere in it someone is taking the piss and they end up being sacrificed on the altar of "oh, it was just this bernie madoff guy, not central bank credit policy".
