Your choice of a job guarantee has a fatal flaw. Technological displacement.

A fundamental component of our economic system is a reliance on the supply/demand curve of human labour as a "self-correcting" input in the production of goods and services. But increasingly we live in an age where technology driven machine labour, AI, IOT, cloud services, etc are a cheaper alternative. Free market capitalism is designed to reduce the cost of production in order to maximize profit so, over time, humans cannot compete.

This displacement is stealthy, knows no geopolitical boundaries and increases exponentially once it gets a foothold in a industry, discipline, etc. all due to the effect of "Moore's Law".

Once the machines take most of the jobs, what jobs will be left? You can't guarantee everyone a job if there is only one job for every 10 humans. And the types of jobs left will probably be at the very low end and the very high end of the spectrum.
