We’re worse off than them - usury wasn’t about high interest rates (though that obviously compounds the problem) - it was about whether interest could be charged on personally guaranteed loans at all.

If all loans were required to be non-recourse they’d suddenly have to be reasonable; anyone suffering too much under them would walk away leaving the collateral.

This isn’t even a death-knell for credit cards; it’d just turn them all to secured ones. But it would be deadly to allowing people to overspend and overextend.
