That's not even close to true, because increasing the minimum wage 1) only affects people who have jobs 2) will cause some of those people to lose their jobs. $1000/m basic income is a vastly better solution because everyone at the bottom will be helped.

Except employers pay less, which would help make them stop complaining about wages costing too much.

There's nowhere near 100% employment. The whole point of this is to bring everyone up and make the social care system simpler.
