Firstly, pay people to go to school. Any subject, useful or not, for as long as they like. The education and mental fitness of the populace is a deep reservoir of Real Wealth.
Secondly, pay (more) people to do community service work: visiting the elderly, cleaning up parks, tutoring kids, etc.
And last, those people still work in the few remaining market jobs: have them work fewer hours! There will always be those who want 40+ hour weeks, but for everybody else, distribute up the same workload over a larger number of people with 20-32 hour work weeks. More people employed, who are less stressed, and a healthier society due to more time to self-improve and spend with family.
Income is only one part of the sociological phenomenon called "jobs". People also want to feel useful.
