Let's eliminate pointless jobs like waitstaff and retail point of sale operators.
People can order from a kiosk, or their phone.
Self checkouts remove the need for cashiers.
We no longer have people who punch buttons in the elevator for good reasons.
Want to be posh and still have these in your restaurant or store? Charge a premium and be prepared to pay people and give them benefits like health care.
Until we can automate cooks, busboys and dish staff those are the food service jobs available.
We need a higher level cashier to watch the automatic kiosks, but not cashiers.
