While the CC companies care more about bust outs, that is a criminal or civil matter. Far more commonly, if one credit card becomes intolerable, consumers just switch to a different card.
For example, recently AMEX got into trouble because of questionable business practices, so it tried raising fees both to cardholders and to retailers. While they lost cardholders, the real pain there comes with the loss of retailers who will accept AMEX.
remember AMEX’s investment arm for the investor class was performing so poorly they changed the name in order to prevent the association with AMEX.

perhaps teh usury laws need updating.
if 30% is ok why not 50% or 100%?
given the fees upon fees for fees, it is essentially usury when the account finally is written off and deducted from their balance sheet.
