You seem to lack faith in the efficacy of ambition.
But since you seem to prefer fast food places, why do you care?
Why would there be any when a lot of people in that profession seem to expect a tip?

Yet that is precisely what happens here in New Zealand: the wait staff get at least minimum wage and there is no tipping. Better restaurants attract better clientele, and there is competition for better wait staff so they get paid better.
Tipping is charity. Nothing more and nothing less. Nobody should be in a position of demanding Charity as a right, and certainly not demanding a percentage of the bill, such as 15% or 20%, for doing nothing more than the job that they are already paid to do.
