Yeah. High-margin, high-end businesses can afford the fees. If there's a space to compete it's low-margin businesses where 3% really stings, even if it's 3% of a smaller gross. I used to work with a company that served mainly immigrants and blue-collar workers, and something lower-fee than credit/debit was a constant conversation (we were partway through building an ACH backend by the time I left, but I don't know if that ever made it into production given concerns we had).
