If I had to take this seriously I'd ask for a UBI cap of 21 Hundred dollars a month. Meaning I shouldn't spend over 21 hundred dollars a month if I don't want to work. If I wanted to save over 21 hundred dollars I'd have to work in order not to have that capped off. Have The Living Wage be $22 an hour for 8 hours a day, 3 days a week. But if it goes over 8 hours a day or over 3 days it becomes $23 an hour. $525 of that weekly wage would still come from UBI & the rest would have to come from the business that's legally obligated to pay the rest. What might happen next would simply be the business making sure you'd only work a max of 7 hours a day, 3 days a week or less. That would help (small) businesses have a healthy work force without it turning into the problem we have with minimum wages right now.
Then when it comes to rent the state government would have to be able to offer $500 a month apartments. If not the state then the federal government. If the state wanted more than $500 rent a month than they might lose out on a source of revenue from the federal government's apartments being cheaper. If someone wanted to make money off of apartments they might have to offer them for less than $500 a month. If this could somehow replace State's sales taxes that would make it even better.
Any Federal Taxes after this I would still want to be a Deflation Tax that applies to top earning businesses that make billions or more. So they still have their purchasing power but with a smaller number. And if another federal tax were necessary it would be a "Billionaire Person Prevention Tax" where the maximum a person could have is $900,000,000. So if a (former) billionaire wanted their business to be treated like a person then it would get taxed like a person. These $900,000,000 millionaires can still put the rest of their money back into there businesses & not die from a lack of money.
