Yes. A minimun wage would be unnecessary with a basic income.
The reason you get a fair price for an orange at the store is because you have a choice to NOT buy it. Most people don’t have that choice to say no when choosing work (if they want to survive…).
And so we currently have a minimum wage, in attempt to make sure workers get a fair wage because people are so poor and so desperate, they’ll agree to work for less than poverty rates.
But if everyone had a basic income, employers will be forced to pay fair wages without regulation. Because for the first time, people will have a real choice not to work, in the same way people have a choice whether or not to buy a product in the market.
