I have no problem with that concept. My superintendent, several levels above me makes mulitple times what I do. The cruise companies are making their tips their compensation. I don't have to count on my clients to tip me. The organization pays me a salary. And don't forget we're talking about these folks making $50 a month. That's not a whole lot anywhere.
I agree with your statement, but I worry about the servers not being fairly compensated and I doubt even their pay with tips even hints at equity.
