Since ours in the US is generally a percentage of the bill, people in expensive restaurants can make more. Do they work harder? Do they have fewer tables so less checks are tipping? 20% tips on 5 hundred dollar tables is $100 every 60-90 minutes, but shifts are usually only a few hours. So maybe $3-400 for a 4-5 hour dinner shift? In a diner you’d are probably half that per table but for more tables and faster turnover. What’s a good wage?
Yeah, I think the big issue comes down to the unreasonable extraction of wealth by the owner class. We should have a massive median wage, something up around 2-3 times as much at the low end. People should not be struggling because if in the 70s they were able to afford a home, raise a family, and go on holiday occasionally and our productivity is many times more than that our wages should provide a much higher standard of living. Instead we are working longer hours, have double incomes, and are still sinking into debt. All that productivity has gone into the back pocket of the owner class, not workers.
