So if you distribute 1000 USD/month to 300 Mio Americans, do you mind to explain where you want to take the money from?

According to [1] the top 3% (>250k USD household income per year) earn in total per month

    127,300,000,000 = 3,800,000 * 402,000 / 12  USD
    vs 
    300,000,000,000 = 300,000,000 * 1,000 USD

needed to fund your ubi. Maybe it's not enough to take from people with more than one megayacht?

While I was being slightly flippant in that, I note that your example of $300Bn as being a completely unreasonable, unachievable number for UBI is less than half the US military budget, and in fact represents about the increase from the pre-9/11 post-cold-war low point. Also that most UBI proposals involve fiddling with the tax bands so that above-average earners see much less or no net increase.

"Do you want $1000 each for twenty years or a war for twenty years" was of course a question that was never on the table in 2002.

Check your numbers: US military budget 2019 [1] is $686Bn or $60 Bn per month vs $300 Bn per month for ubi.
