Yes, but if tipping didn't exist for that particular industry, the pay would likely have to be higher, otherwise people wouldn't take up on those jobs.

Take Uber right now. I bet the founders are only doing this because they've noticed Uber drivers are starting to leave them because they are unhappy with the pay. So if they did nothing, Uber would lose those drivers. But instead of paying them higher wages, their "solution" is to coerce customers into tipping the drivers.

At the same time they pretend the Uber driving costs for the customers didn't actually increase because the customers "don't have to" pay the tips, so Uber can continue to pretend its tariffs are "competitive" with its competitors. But as we all know from other industries where tipping has become "expected" that this is not how it works, and the costs have indeed increased for customers with this move. Maybe not in the short time, until everyone gets accustomed with this move, but definitely in the long term.
