Congratulations! You are obviously very clever to have achieved so much. I think, however, there are many people who, for various reasons, do not do so well.
For this reason, I am in favour of a Universal Basic Income. No child should be without. No person should do without. For what reason are there so many homeless people and very hungry people… so hungry that the food banks can’t keep up.
Immigrants probably have language problems which would make everything more difficult. People are persecuted for their colour or their gender which probably makes getting some jobs more difficult. I doubt that people who live comfortably with six figure incomes will benefit from UBI. They will just probably have to help out somewhat with their income tax or other taxes.
I also think that most people prefer to work unless they have serious health problems of some sort. I would think that it would make most people feel more useful and happy with themselves.
