cashiers were replaced by vending machines. anyone see a Best Buy vending Machine or Japanese vending? cashiers are about as useful as full service gas attendants. They aren't.
The solution is a society without a "work or die" mentality, like you have right now.
We have passed the need where everyone must have a job. We can't keep inventing new jobs like influencing just to give everyone one.
It is okay if there are some members of society that don't contribute much. We aren't cavemen anymore where every person needs to work so the group doesn't die. Hell we already have business owners and landlords, who offload all their work onto others and do nothing for society except own stuff.
