That’s misunderstanding the human spirit in my opinion.

Maybe some would coast and be happy with whatever the basic income is, but I suspect many others would strive and do more. If not for survival and the privilege of having food + a roof (like it is now), then mostly for the satisfaction.

I don’t subscribe to the theory that giving everyone a basic income would instantly turn everyone into a couch potato. That’s just not how a healthy person thinks/functions. At least not in the long term.
