After segregation, rich white former slave owners and racists pushed entire tipping culture onto service workers, from whom many were POC. That way, they paid “same wage” regardless of color, yet customers gave extra money to white people only.
Even today, tipping culture is broken evil system of capitalistic oppresion which is unique to USA, as many countries while still allowing tip make sure service employees get paid living wage and tip is just a nice bonus, not a means to survive.
Some countries consider tipping straight up rude.
Saddest part is that some especially waiters are soo gaslighted into it, they blame low tipping or non tipping customers instead of employees who use this narrative to pay basically no money.
I dream of a new usa, unionized, where people get paid livable wage and dont rely on randomness of tipping.
Remember. Vote for your rights, join union, read socialistic teachings.
