No, it's "inherently low value" because most people can do it, and there will always be people desperate enough to do it. In fact they'll do worse jobs for less than a poverty wage, if given the opportunity. We could pack them into tiny boxes and send them underground to die of preventable diseases, then say they owe US money for the privilege. We enact labor laws because we can/have done this and find it distasteful. Being a server is not an "easy job". I wouldn't trade it for my developer job, even if the pay was equal.

The business and customer are getting an excellent deal because the model is anti-competitive and driven by human desperation and inequality. Which is why we have a minimum wage to limit the exploitation. The job isn't easy, and it is an important one. Restaurants for better, but mostly for worse, are staples of our society. They're valuable jobs.

These people are giving up their entire lives basically. All you have is time on this earth, and they're asked to give all of that for nothing, so you can live in the lap of luxury. I don't want to live in a world without bartenders and servers. I consider their work valuable, and think they deserve fair pay.
