> Any income that can sustain a household without any pressure to grow as people will probably hinder their progress more so than help them

Are you basing this off of any familiarity with poor Indian culture?

Why do you expect "free money" to translate into "lesser progress" rather than "progress of their choice"?

Here's a different question: Have you learned more through self-directed learning, or other-directed learning? How have you chosen what to learn, and would you still have that drive-to-learn if you had free money?

Remember that UBI is in addition to salaries / wages, not instead of.
