A fair wage is when you can afford all basic necessities and have money left over to buy reasonable things that you don’t need but want. Anything below that is not a fair wage.
Dude you can buy a LOT OF RICE AND BEANS AND VEGGIES LOADS OF EGGS & MORE protein. Things you want come AFTER each of 9.000.000.000 get the aforementioned (and basic shelter, basic clothing, etc). Before half the world doesn’t have that, you have no right to extras.
