I’m not saying the system is what you should be more grateful of, but minimum wages were fought for by people who didn’t earn enough to pay for their basic needs. They acts as flood gates against greedy employers. Doesn’t mean the rest of the system is worth appreciating.

The need for lowering the price of goods doesn’t change when there would be a basic income, but you are right people are more willing to accept a low wage of they are threatened by starvation and homelessness, a basic income will definitely be a good thing for people who currently are earning a low wage.
