While you may not be envious of another person's wealth, we don't live in a world where everyone is like you. So the safety of the wealthy which could include you is at greater risk as more people are jealous of whatever you were born with. If you're born pretty then others will be very jealous of your beauty and some will even want to ugly you up so as to balance the playing field in their own favor. If you're born rich then some people born poor will be jealous that you were born with a silver or gold spoon. If you were born with some rare talent or were a child prodigy then some other student in class is likely to want to bully you because of it.

How are the wealthy (who were born with rare capabilities) supposed to deal with the propaganda of the future when there is no basic income and propaganda riles up others to create jealous rage mobs intent on taking from people who have too much or who have been too lucky? UBI is as much about security as it is about anything else.

Lack of UBI ultimately leads to social conflict, social disunity, and one way or another people get made to pay for their crime of being too lucky. The unlucky could simply feel that the lucky owe them something.
