I interpret it differently. The high interest rates cover the defaults from the deadbeats that the banks shouldn't have given a credit card to in the first place. So why do they give out cards they shouldn't? To skim profits from the money movement, of course. And who's providing the money they skim? The ones that pay off what they owe.Wait until they start cancelling cards and reigning in credit.
Dumb piece of shit has no idea what he's doing.
This makes some sense , from an investment angle
