> the kindly rabbi who performed your bris mohel performs a bris, not a rabbi > It’s why you’re receiving 2% cash back on your credit card while your neighbor pays 12% on his. This is mostly because merchants pay a fee, and the CC company kicks it back to you. > I’m not asking why Wealthfront helps itself to such margins, which is obvious and perfectly normal, but rather why the market bears it AirBnB and Uber and real estate agents do the same thing [price-proportional fees, not cost-proportional fees or flat fees]... Anyway, it's not as bad Blake rants about. Flat fees hurt the least-wealthy customers. 1. It's progressive. Wealthier customers pay more. That's good for sociery. 2. It's not inherently a scam, anymore than airline tickets or home sales. Ultimately, they compete in the market, and have to price competitively. Companies will lower prices to attract customers (if competition arrives), but maintain their profit to stay in business.
