Also, the solution to the automation problem is not higher education, the solution is the return of the skilled laborer. You can't automate a robot to drive to a customer's house, cut open some drywall, fix a plumbing leak, restructure some electric piping to a new section of the wall, install a socket, make a report and get it signed by the customer, get payed, drive back to the company hub, and finally give you the money. Hell you can't automate a robot to make custom dragon blood forged steel swords, which we'll probably need for the zombie apocalypse. Bachelor and masters degrees are currently too easy to get to the point even a monkey could get a bachelors these days, specially if it's a wealthy monkey. The result is that GOOD plumbers, electricians, or dragon blood forged steel sword making blacksmiths are so hard to get this days because all the offspring of skilled laborers want to go to a fancy school to be doctors, lawyers, or architects, because it's all the rage to get a university degree this days.
For what it's worth, most people actually doing the "cleaning up after the elderly" job are certified nursing assistants, who often earn basically a notch or two above minimum wage.
The pay might be shit, but we'll make it up in overtime:)
1000 yen per hour is about £7.90; the UK minimum wage is £5.93 ((if you're over 21) but there are some tax breaks and benefits available to some low paid workers). There are plenty of jobs at that minimum wage, and many of those jobs will be as dull as checking gaskets.
