I agree that we can't begin to have a conversation until a baseline is set. Say that baseline is food, shelter, and health. The question then becomes are we doing that now and is it working. I would argue that we should offer that as a bare minimum but that bare minimum should be highly regulated because the technology exists to do just that.
For shelter you are provided a place to live, this place is paid for directly by the government, with electricity and water also taken care of directly. You do not get cable, you do not get internet, you can go to the library in which a library card is provided with housing.
Health, the system is set up where you see a list of pre approved doctors. You are assigned a single doctor, only this approved doctor can write you prescriptions. Your information is flagged in the system so that if any other doctor writes a prescription they are subject to fines or loss of licensing. If out of town emergency then said doctor must consult with your pre approved doctor.
Food, no longer are you responsible for a debit card or buying what you want. Based off of age and household you will be provided with the government version of blue apron. Nutritional approved food is provided to your housing weekly. If the government is going to take care of you, you will eat your vegetables.
Transportation, i would argue in today's society you need to be able to get around. Free bus passes and other public transportation should be provided.
So now you have food, shelter, health that's highly controlled. You are cutting down on obesity, opioid use, etc... these are the bare minimum, you exist in society but you don't have Internet and TV etc... you work for those. Additionally for you to be allowed those I would propose you must hit a certain threshold. No odd jobs for 100 dollars so you can sit at home and watch cable. Sure seems like work release prison, but it's not your money and your sole focus should be improving yourself to get a job. I would also say an expansion of job training programs and the like should also go into a system like this.
