Actually, all the money spent on welfare, plus about $100bn (not very much), amounts to $7,125 per person per year in 2012. The rough growth is 3.5% per year or something crazy (total amount of personal income increases by roughly 3.5% per year), so estimate $7900 in 2015, or $658/mo in 2015 for each natural-born, resident, American citizen over the age of 18.
Even at over $1/sqft (I paid less than $1/sqft to rent an apartment), a livable, 224sqft apartment can sell for $300/mo, leaving $358/mo for food, utilities (heating 224sqft isn't hard--I heated my living space for $60/mo for 4 years), soap, toothpaste, clothing, and the like.
By using a dedicated flat tax replacing OASDI, we tie it to total income: regardless of wages, operating costs, or price dynamics, we get the same money. If businesses automate and don't lower prices, they make a bigger profit (not paying labor), and the dividend increases by that proportion (10% more profit means 10% more in the dividend); if wages increase, profits slim down, and the rich come closer to the income of the middle class, we're taxing the middle class same as the rich to fund the dividend. No matter what the shape of the economic situation, we get the same amount of money.
$1.28 trillion comes out of the federal budget, and an extra $0.34 trillion imagined from the state's welfare budget. I actually leave that up to the states: there will be less need, therefor they can slim their welfare programs, possibly even eliminate them; but I'm against mandating anything in that regard. $1.62 trillion total in 2012, $1.72 trillion was what I estimated as a minimum; and the current situation probably changes the numbers a bit, such that we can implement a somewhat smaller tax and reach the same market situation (I haven't examined this yet, but it's a distinct possibility).
The total tax difference is some 3% in the worst case, and that's unbalanced; I can get it down to 1% by adjusting the base income tax brackets (which are slashed in half, mostly), and the worst case falls on the high-income earners. The current public disposition is a 50% or greater tax, rather than a 39.6% tax, on this class; I propose a 40%-42% tax, only if necessary to meet my end goals, which is vastly smaller.
It works. It makes the poor and unemployed a continuous profit source, creating a market opportunity to support them and become very rich in the process. It has a 15-year transition plan for social security (after which current retirees are grandfathered), and a risk control in that it doesn't decree the dissolution of state welfare (which largely drops state welfare costs, but leaves states room to catch my miscalculations and implement some sort of food security for large, unemployed families--a thing that shouldn't exist, but the world is a shit hole). It encourages work by continuing to pay out the same monthly dollar amount whether you sit at home watching TV or go CEO for a major oil company making billions of dollars.
Of all the UBI plans out there, mine is the only viable one. The idea is not new, but it's so newly integrated into the political mindset that people treat it like a secret sauce you can pour on top to make everything better. It's a very dangerous and volatile concept, and *will* destroy the economy if implemented incorrectly. I need people to catch up so they can suggest improvements, instead of "hey let's give everyone $20k/year and pay them $5k/year for each kid they have!" stupidity that will only lead to hyperinflation and a Reichmark economy.
