Please. Have you ever lived in poverty? The people who climb out will tell you what other poor people are like. And I'm not just talking about poverty. Look at what former Soviets have done in NYC, especially Brighton beach. They live out of the projects but stereotypically drive BMWs. The average poor person is not your aspiring PHD father, its someone who wants a quick buck for the immediate future.
UBI is textbook ivory tower politics. Poor people aren't just poor because they have no money, and by and large throwing more money at them won't solve anything.
Now if you want to argue that the waste is worth it because of people like your father, thats plausible, but acting like UBI is the answer to poverty is absurd. Not to mention that you're essentially setting a demand floor which will "unnaturally" interfere with the economy. Another potential can of worms.
