Part of the downvotes may have been due to this inclusion:

>Taxes gathered this way should found basic income.

...which is going to turn off some people, while others will consider it an unnecessary political tangent.

That's just an idea. I just think it should not be part of normal government budget because it could increase goverment spending for usual stuff and when that's increased it hardly ever goes down.

Why would the universal income spending be any different?

It might be different because there's no BI yet. BI is simple so the rules can be written to be simple too. Like setting up fund and spending on basic income not a fixed amount but last years fund income instead so the fund never gives away more than it earns.
