Finland wrapped up their experiment with the Universal Basic Income earlier in the year. Once they established the ‘baseline’....they came to realize that you couldn’t make it work without massive taxation. In this case, $500 a month...it might be set low enough to develop for a while, until everyone whines that it’s not enough.
Wussy Socialists! 100 people out of 77,500 residents below the poverty line?! Wow, a whopping $50K/month...go big or go home...go for the whole 77,500 people. It will set you back a mere $465 million a year! May be a bit hard due to the whole city budget being $709 million, but if going Socialist, go Socialist for goodness sake!
