I know i'm just going to get downvoted to oblivion, but has anyone who thinks this image is accurate actually worked as a waiter/server?? Because this is honestly one of the worst examples you could've picked to prove your point.
Because working at a massive nationwide chain restaurant, my girlfriend makes 40-50k a year as a waitress, 80% of it is cash which she can report only around 10-20% of it on her taxes without raising any suspicion from the IRS, whereas i stood to make ~40k with my biochemistry degree that took me 4 years to get and 70k if i'd have paid out of pocket and not received a scholarship. And my girlfriend isn't some exception to the rule, bartenders on average make a lot more. This image also doesn't include the fact that most people who work at the restaurant either get A) a free meal per 4 hour shift if it's a chain, or B) between a 30-80% discount off anything they buy at that restaurant.
If you want to talk about the Back of the house, aka the prep-cooks and dishwashers and the likes, then yes, this statement is accurate, but then that'd be mostly considered the "food" industry and not the "service industry" by most statistical entities (meaning that one works with food the supermajority of the time, and the other works directly with customers the supermajority of the time). They get paid a LOT less than your waitress or server, mainly because a waiter or waitress is a salesperson at their core. They up-sell you on items, are mainly responsible for if you return to the restaurant or not by dictating your overall experience there, recommend different foods or alcoholic beverages that "compliment" the entree, try to convince you to order more ("are we feeling any desert tonight? we have a wonderful chocolate lava cake!") and so on and so on.
Basically my point is, if you asked most servers on here, they'd prefer the tipping culture in america, because although it sucks to be the consumer (who pays the tip that business owners force onto you) most servers make a lot more this way (as evident already by a lot of the replies from people claiming to be servers in this thread).
In fact the REAL problem is, that in america, your options are to go to college and generally make NEGATIVE money for a minimum of 4 years (taking out student loans, aka debt, to get at minimum a bachelor's) and then, with no guarantee of employment, hope to get a job that will net you less than the average waiter/waitress makes BEFORE even taking into account the payments that are due on your student loans (with interest). That'd be a much better talking point and an issue to rail against.
