> The opportunity here for a startup bank is to replace credit card spending in the USA. The potential earnings are huge if you can get consumers to spend on a debit card instead of a credit card (because the rake is higher).

I think the converse is true. Card issuers earn 1 percent points higher interchange rates on credit cards (2.60%) than debit cards (1.60%).
