It depends. Predatory salesmen are happy to oblige a customer's desire for a $299 monthly payment, while glossing over the 84 month schedule and 12% interest. They have a very short term view. Uninformed customers are like shooting fish in a barrel.
A mainstream bank takes a longer term view. They offer financial literacy info for customers who are interested. If a customer overdrafts less frequently and is able to leave significant amounts of money deposited the interest spread is more profitable than collecting overdraft fees.
The predatory loan market is a fringe market though, and it's not even that lucrative because delayed payments and default rates are so high (and bankruptcy rinses the lender).
Don't confuse the existence of people who profit on inefficiencies as being a sign that the system works best with those inefficiencies, or that those inefficieces are even particularly profitable.
It is my impression that predatory car loans are basically ubiquitous
