Perhaps I'm missing something, but how BI accounts for the fact that not everyone has the same basic needs or expenses? Someone will need expensive medications, another in-home care services, parents will need to spend money on kids, pay for daycare/schools, etc. Writing the same check to everyone might save you from bureaucracy, but it will put vulnerable groups in a relatively worse position, while single healthy people will profit from it. Also how do you avoid just deepening the gaps between the poor and the rest? Poor will still be getting approx. the same amount as they do now, but the rest of the population will get extra money they didn't have before, so the difference will be even bigger? Also wouldn't this extra cash flow create inflation, raising all the prices?
