And that idea sounds pretty good. But in a nation with hundreds of millions of people, like the US, the government may not be able to find a job for everyone.
It's not much a stretch, just encourage businesses to file openings in a database, and to check for matches when folk ask. If it's done for millions, it's not much a stretch to do it for hundreds of millions; at most, you could decentralise the process (not by states, though, since that would be very disproportional and is a dumb thought to hand anything to the states as they are now).
Liveable wage = 1.9 (adjusted) $ each day, as said by WHO.
Does adjusted mean its in a country where you are used to getting no food and a burger (400? calories) costs that much, I don't think that's liveable.
Just pretend it's the Big Mac index, and adjusted for how many Big Macs you can buy.
