Finally, for now, and also "in fact", Friedman is generally regarded as the father of a similar idea--the negative income tax--which already exists in the form of federal and state Earned income Tax Credits, which provide taxpayer,--rather than employer (for better and/or worse)--subsidization of low-income employees who do not '"earn" enough-- from "paid" employment alone--to pay for their most basic living expenses. 

i also fully expect the familiar, ongoing,  seemingly never-ending debate between those who want to mandate higher minimum wages paid by employers--but which are usually passed on to consumers in the form of higher prices for many goods and services--and those who want taxpayers to subsidize low-income workers, or at least those who have something called a "job"--and who are not yet classified as ostensibly "self-employed" independent contractors--who now are expected to be able to afford to pay for ALL of what were previously at least partially "employer-paid" expenses
