Unfortunately, this approach will result in exactly the opposite of the intended outcome.

Increasing the average cost of using human labour in the economy will only accelerate the speed with which machine labour replaces it. The impact on the supply/demand curve for human labour is the real element at work here. Machine labour, AI, IOT (Internet of Things) all contribute to driving the incremental cost of production toward $0. Humans cannot compete. The increased profits coming from lower cost machine labour will continue to shift to those who own it leaving the rest behind.

The true solution lies in rethinking how we "measure" the value of human endeavor. Our legacy is to measure it by size of one's paycheck, or value of owned assets. Continuing to do so is unsustainable.

We have the chance to properly value those aspects of being human that machines don't have (yet) have. UBI or something similar is the way to provide the freedom of opportunity to do that.
