Basic income only works if you eliminate exposure to the rentiers first. Otherwise, if you give out $1000/month, all the prices for unavoidable expenses like housing, transportation, energy, food, and utilities mysteriously rise by $1001/month.
But without basic income, all that is happening anyway, and all that extra blood has to be sucked out of wage increases instead of stones.
Seems like one strategy would be to fund BI out of a tax on unearned incomes.
