At some point, if the people don’t say enough, let it all come crashing down, and rebuild a more equitable system
Who's organizing this? Your withdrawal isn't part of some collective movement, it is solitary and impotent. It is harmful. There's no board room hosting the league of evil medical barons, no agenda item about how Allonzee stopped donating blood so they'd better start taking things seriously. You're not changing anything, and squeezing sick people isn't a necessary step in effecting change anyway.
There's no "we" and there's no collapsing. These systems persist despite your personal rebellion, because they're really good at persisting until faced with overwhelming collective action. Until then, fucking help people.
Sorry friend, it's not really about you. But a lot of good people who care about inequity have let their pride convince them that systems will implode if they personally choose to stop participating in them. That's not how it works. The only people feeling any hurt are the innocents in your own communities.
