The minute we got off the plane in Tokyo we were met by a greeter pointing people to the escalator. Not that you could miss it, that was the only exit.
In the city you could see people guarding potholes. Bus stations (not particularly busy) would have a couple men at each station that would help arrange the passenger luggage: something usually helped by the driver in the West.
Once we took a night stroll in the city, meeting a roadwork on a deserted street. There were 3 men along the fenced dig basically showing us to walk around it.
Can't see any of that sustainable if you pay people full wages.
