"This is my biggest concern with the idea, which I don't see being addressed (checked the entire conversation on this post to date). I don't think having the vote and having the basic income is compatible with each other."

If you have well-enough educated, hopefully reasonable people I don't think this will become an issue. Swiss recently voted down to get more holidays ( http://www.telegraph.co.uk/news/worldnews/europe/switzerland...) and it wasn't even close of getting through. Now this of course doesn't prove anything (we also voted to ban minarets for instance, which definitely wasn't very rationally based), but it shows that people will not just take the short sighted approach only thinking of immediate rewards and instead try take the whole economic outcome into account.
