This seems to be you choosing to live in an idealized form of your future vs the actual reality of today. My question is, if you're choosing idealized anyway, why stop at a mundane ideal where anyone has to work for minimum wage at all? Unless you've baked the lower class labor category into your ideal future?

You not tipping doesn't improve anyone's material conditions. You choosing to give money to the exploitative companies does affect material conditions, negatively! To me it sounds like you're trying to doordash your cake, eat it, have it, not pay for it, and get paid for eating it, all at once!
