We're not bright, as a species.
The people under paying labor would probably disagree with you.

Unfortunately US politics means this won't change any time soon. Evidently it's simpler for every American to carry around spare dollar bills every day than it is to pass meaningful legislation.
One practical solution would be to close the minimum wage loophole for tipped employees. The difference between the two minima is the presumptive value of the normal tip, so this is a means by which you can coordinate an instant and universal change from relying on tips to having no reliance on tips. It's not exactly ideal, given that everyone knows waiters typically make a lot more in tips and evaded tax than that difference, but it is at least consistent and nominally fair.
I am not sure what other practical solutions you might have in mind.
I always find these sorts of arguments vexing - people act as if we can just 'decide' as a society to change something, and it is that simple. I can't 'decide' for society to do anything, unless we organize, coerce, and perhaps legislate.
"What is a tip? It’s a multiplier of menu pricing and as menu prices have gone up, so too has the multiplier over the course of my career which is now 30, 31 years.Tipped employees, happily for them, are making about 300 percent of what they were 31 years ago. During that same period, everyone in the kitchen — the dishwasher, non-tip eligible employees — have seen their hourly income go up about 20 percent."[1]

There's been an interesting move by Danny Meyer and Tom Colochio two well-known and very successful restaurateurs in New York City to abolish tips in favor of a flat service charge to be shared amongst everyone in the restaurant.
Danny Meyer talks about the history of tipping in the US in which he claims is rooted in post-Civil War racism and the old Pullman cars.

Interestingly enough the practice seems to have originated in Europe however before dying out:

My guess is that it is more transparent to both the customer and the staff who may view this development with some suspicion at first.
