Yes? I don't see how helping my fellow citizens, and myself, at a vanishingly, immeasurably small cost to myself is a bad thing.

I agree with your sentiment, but my credit card fees are definitely measurable.

Mine are minimal; I pay no annual fee and no interest if I pay off in time. So they're effectively just the transaction overhead, which debit demands as well.

Minimal in terms of direct costs to you, but merchants pay 2-3% on EVERY transaction, and I can guarantee you that does end up baked into the prices you pay.

Better than a system that can't manage that much.
