Take the over half-a-trillion dollars the U.S. spends every year on its military budget, weapons R&D budgets, any major funding that is tied to war efforts, “defense”, fighting, etc. and instead use that money towards providing EVERYONE in the country (regardless of their financial standing) with free basic living necessities like food, water, electricity, shelter, medical expenses, and other quality of life implements.
Should the cost exceed the 500+ billion dollar yearly expenditures from said budget (it probably would for the first few years at least, covering initial startup costs such as building housing, etc.), hit up the collective 1% , or even the top 5-10%, wealthiest in the country to help foot the rest of the bill.
All those who contribute financially from their own funds, get their names published globally with recognition of their contribution amounts, and we make these contributors into our new celebrities in society.
