My suggestion is a type of UBI that is immediate, fair, and would immediately be effective at easing some of the desperation these people must feel.
I propose a tower that drops money. $1 every minute. The price of such a tower in dollars would be just over a half a million dollars per year. It would serve as a tourist attraction, and a way for someone needing a few dollars to get them without begging, without stealing, without stigma. It would put dollars in people's pockets that would be spent at nearby businesses. I don't see a downside.
The town I live in, Pine Bluff Arkansas, has an organization called Go Forward Pine Bluff. They waste so much tax money it's unbelievable, and the things they do don't benefit the people.
I'm fighting them as hard as I can, and I hope to someday build a tower like that in this town.
