Re: UK Perspecitve
Maybe your base salaries are higher, allowing low wage slaves to actually survive?
In the middle ages tipping was called "alms", but since charity is considered demeaning, it was eventually renamed to something positive, supposedly a "bonus for outstanding work". Like, "Hey, that was fantastic, here is a token of my appreciation". Except of course it has little to do with the quality of the service, it is just supposed to turn an abysmal income into a very bad one.
But then hey, we're in a free market: Nothing prevents those people from being millionaires themselves. If they're starving, it's because they're lazy, isn't it. /s
