It doesn't work that way either, but that's the rationale.
Forcing people to tip to ensure people get paid enough money is a consequence of the system, not the reasoning why the system is implemented.
And/or a craven attempt by employers to further deflect any responsibility for responsibility for paying their employees. I noticed that the Curb app bumped the default tip rate to 25% at some point. I'm guessing that's somehow, directly or indirectly, leading to them or taxi companies getting to keep a larger cut of the fares.

Indeed. The on the ground reality is that tipping does not serve this purpose. I don't know if it ever did, to be frank. Studies[0] generally show little to no correlation between performance and amount tipped.
And the reality is that tipping is the reason invoked in many state laws for paying restaurant workers less than minimum wage. Tipping is the reason they get paid poorly, and I always find it problematic that people invoke tipping as a way to help people, when it is the cause of their low wages. In those states, tipping is a big win for the restaurant owner. The customer pays more money out of his/her pocket, and the waiter often does not get much money.
Unlike others, though, I do not consider this wage theft (even at a moral level). We don't tip for many other services that we receive, and the problem of how those workers are compensated doesn't cross our mind. Why do we insist that tipping some category of workers has a moral component whereas others do not? Fixing those laws will be a challenge as long as tipping is commonplace.

(Yes, I do contribute to their poor wages by tipping. Have to conform somewhat to society!)
So it sounds like it is absolutely used as a bad way to supplement wages.
Tipping really is a method for the employer to hold onto as much money as possible at the expense of staff.
