I should point out that the structure of the taxes to fund a basic income are a very, very important implementation detail. As a pragmatic matter, I'd want to phase out existing programs like Medicare, Medicaid, Social Security, SSDI, food stamps, educational grants, etc. and simply redirect their funding streams to a basic income--best to pick one battle at a time.

But my ideal taxation scheme includes an abolition of corporate, income, and sales taxes, and a replacement of them with aggressive taxation on goods that are highly inelastic and cheaply taxable. Think land taxes, except updated for contemporary times. Yeah, wish me luck with that.
