Having the means to protect yourself is the baseline definition of a secured credit card. That’s why it’s secured. You’re starting with some positive balance and spending your own money. That’s what debit cards are too. The liberty banks take is choosing who gets to benefit from their normal spending of their own money being considered as credit at all.
0. for many aspects of life you need positive credit history to live at all
1. debit cards don’t help you build credit
2. secured credit cards (your own money! not borrowed!) do
3. both function almost the same way, but the latter is much less equally available
And if you think “living on borrowed money is a fraud”, I suppose that means you think only independently wealthy people should own homes? Nearly no one could afford to buy a home anywhere without a mortgage.
The first was the scam of debit cards and secured credit cards being treated fundamentally differently. They both operate basically the same way for customers (you’re only spending your own money, it’s not credit in the lending sense), but debit cards are a profit center with no credit reporting for the customer and secured credit cards can be recommended or not in any discriminatory way anyone wants (which they are).
