I’m not kidding whenever my answer to “how do you pay for it” is “take it from the cops”. If you give everyone enough food, crime goes down. If crime goes down, then you can spend less on cops. Cops exist downstream of problems. Keep doing this for every problem and you keep spending less on cops
If I’m building my ideal world, food is free and so is delivery. And delivery drivers don’t have to stack orders to make enough money to live
