The best argument in support of UBI is that poor people spend it locally.
Rich people tend to spend most of their money on luxury goods that most of the time come from other places. They generate wealth elsewhere.
Poor people tend to spend on basic needs mostly supplied locally: food, shelter, transportation, sanitation, etc. Because of that UBI's multiplying effect on generating more income is powerful.
Conservatives like to say that low taxes for the rich benefit everyone because they generate progress, it is called supply-side economics. I wouldn't advocate high taxes "per se" as in taxes to give money to the government. However, it is possible that high taxes can have a much more powerful impact on development if the money is spent wisely. However, I accept that politicians spending public money is a rare exception, not the rule.
