Basic economics tends to quash the theory of "just giving people money quashes poverty". Wants and needs are limitless while resources few. The problems with pumping money into a minimum income include but are not limited to:
1. Devaluation of fiat money/increase of inflation
2. Worker fatigue (think voter fatigue not actually tired fatigue)
3. Mismanagement of money by it's owners
4. Dissolution of power (Power in political science terms is defined as one's ability to distribute limited resources on a large scale, having said that the dissolution of power causes anarchy. That doesn't mean minimum income will plug us into total dissolution of state, but it in a smaller, less-butterfly-effect way can cause more chaos)
5. State debt
The list goes certainly.
