Okay, that's an interesting take on the matter. I think in a world where money buys the legislature you'd end up with basic income repealed (or not passed in the first place) and as a result, it doesn't serve the intended function.
That's actually why I'm really in love with mayday.us; Lawrence Lessig's PAC to get money out of politics by supporting people who want to do actual reform rather than just saying that want to. If we can actually vote the bastards out and get better people who won't be bought in, we've got a chance to shake things up and maybe fix some of the underlying problems that basic income seems like a solution to.
I maintain that everyone could stop working and prices could rise enough such that basic income is a joke and everyone has to work again in order to eat, which kind of defeats the purpose of basic income.
But I do appreciate your response.
Or the price of labor goes up. In a system where money buys the legislature, your only real recourse is to say "Fuck it, I'm out." Basic income would enable labor to vote by withholding labor. That's a feature, not a bug.
