Exactly, that's the discussion we need to be having. UBI is intended to replace other welfare programs that are riddled with bureaucracy and are highly inefficient. Social Security spends an incredible amount of money on lengthy application/interview processes, regular case reviews, and fraud investigations, most of which would be eliminated if replaced with UBI.
Maybe we could decrease the bureaucracy without giving away money to everyone rich and poor. UBI is a strange concept that doesn't function in nature. Why would any society feed parasites who spend nights drinking or taking drugs and days begging and buying supply of alcohol and drugs for the night?
We also need to consider that minimal income will deter crime and reduce healthcare costs as it will keep people from being completely destitute and homeless. I don't know where other posters live, but the homeless problem is accelerating badly in the US. People can turn a blind eye to it and say they don't want to give these people handouts, but they will end up paying for it one way or another through the healthcare and prison systems funded by their tax dollars.
Do you really believe that a mugger who spends his days stealing phones and wallets will stop doing it because he's now getting 200 from the state? How is it going to decrease crime? Poor people don't steal to live. They usually beg or starve. Criminals usually have more than they need to survive.
