Hey, I’m just a lurker on this discussion, but I’m going to assume you’re asking an honest question here and not sealioning. If you really want to take action, I’d recommend looking at changing policy at the local level. I believe California has recently passed a couple laws that do things like disallow mandatory gratuities for large groups, and increase minimum wage for service workers. So if you want action items:

• easy: look up the specifics of those California laws, and look up similar laws across the country, and see if any of them could fly in your municipality or state. next time the politicians come calling, say: “what are you doing to implement [policy]?”
• medium: if you don’t think any existing policies would solve the problem, then try to think of what policy would.
• hard: instead of tipping, save up that cash, keep track of it. figure out what organizations in your region could help implement those policies, contact them directly, and tell those organizations that you’ve saved up money that you’re willing to donate to help implement better policies.
