Did you? You asked a question about Social Security policy, in a thread that's arguably about individual tipping practices. Perhaps you regard the former as an illustrative thought experiment which helps reason about the latter via shared principles, but it's a shame you didn't elaborate on it because as it stands, I regard it as a non sequitur.
It's irritating to be accused of not engaging, when you've twice ignored my main point that expectation of tips lowers the posted price and makes life harder for all of the drivers/servers. Making life harder is not a benefit. I tried to probe for what is not coming through to you this third time, with another case where the legibility of a cost is shifted to no benefit.
I can see how that might be irritating. Good thing I haven't done that.

That's not a point. That's a claim, which you have not persuaded me to accept.

If only you had been clear that that's what you were doing, I would've told you that what's not coming through is the casual relation between tips and wages. You seem to believe tips necessarily suppress wages. I see no particular reason to believe that's true.
