As a proponent of this kind of program, I totally agree that $20k is much higher than we could presently afford. The numbers look substantially more practical at 1/2 or 1/3 that, despite replacing less.
That's actually per family/household. So per-person it'd be a third of that, based on my assumptions.
Something that I haven't heard mentioned is whether BI payments are subject to income tax (like Social Security payments are). The numbers are low enough that the taxman won't take much. Going by the current IRS brackets, and assuming they had no other income (worst-case scenario), the per-person yearly payments of $6,666 would mean a 10% cut, leaving $6,000, or $500 a month. Which is a little more than what people spend at the supermarket.
