“can’t solve the problem as long as capitalism exists, so may as well contribute to capitalism while patting myself on the back and pretending i’m sticking it to the man by helping them exploit workers” is such fucking bullshit. “i can’t change the world so may as well contribute to the fucked up” is exactly what keeps the practice sustainable.
you are only contributing to wage theft by deciding you’re a hero for not tipping.
if you want to try in other ways to make effective change in society? go for it. do that too. but don’t hit no tip and then go jerk off publicly over how sexy you are for fighting capitalism.
