Good morning Cactus Flower,
I've always thought 'credit cards' created a flawed model & dependency.
'Instant gratification', instead of working towards, living beyond our means.
Over time folks learned to tolerate interest rates higher than loan sharks offer, up to 36%.
I use credit cards, but only for convenience. I always pay when the bill arrives, never owe/pay interest.
I think we might be better off without them & consider the 'UNFAIR interest' we would deprive those institutions ;)))

DO SOMETHING!
