if you are a highly paid technology worker, when you go to service establishments where people are working hourly and are desperate to work 40-50 hour weeks just to pay their rent and feed their kids, you *tip*. *generously*.
the US has an insanely out of control income inequality issue that is very intractible and structural. If you are so fortunate as to find yourself on the winning end of it, as is the case for a vast portion of Hacker News members, yes, (WHILE SAID STRUCTURAL INEQUALITY CONTINUES TO NOT BE SOLVED BY OTHER MEANS), you should be transferring to the members of your local community who are not so fortunate (AND ARE EXPLICITLY ASKING FOR TIPS AND/OR WORKING WHERE TIPPING IS CUSTOMARY) and you should be happy to do it.
hi - not as *a subsitute for raising the mimimum wage*, of course not, of COURSE wages should be raised. of COURSE if everyone were paid fairly in the first place, THAT WOULD BE GREAT. however, at the moment, the federal minimum wage hasn't been raised in 14 YEARS, so FOR THE MOMENT, until said inequality issue can be structurally modified, workers really could use tips. that's why they are asking for them.
