One of the criticisms of the living wage is that it takes no account of the relationship between the cost of an employee and the value of his or her work.
If the cost gets out of kilter with the value the employer is going to look for alternatives like this:
. . . In the new concept video, Pizza Hut swaps out the tables at its dine-in restaurants for massive touch-screen displays. Once you sit down, the first thing you’ll do is place your smartphone on the electronic table, activating the display and automatically signing into your own personalized account. Then you’ll design your pizza using the interactive screen before finalizing your order and paying through your device. Finally, the display lets you and your friends play popular mobile games while you wait. . .
This is only a concept, it will be a long time before it is implemented, if it ever is.
People will still be needed to cook the pizzas, bring them to the table and clean up after the diners but technology like this could reduce the number of waiting staff needed.
The more expensive staff become, the greater the cost of employing people in relationship to the value they provide, the more attractive technology to replace them becomes.
