> the answer to the variety of problems that plague Chicago's South Side, New Orleans, or any number of troubled communities?
No one (government, private sector, etc.) has the answer to those problems. Those are really really hard problems that require the cooperation of non-profits, local governments, religious institutions, families, etc. I don't think they're expecting to be a silver bullet.
Basic income on the premise of infrastructure renovations is something I'm fully behind and I think many more citizens would be too, specifically those getting by on food stamps.
That's exactly why billionaires donate to their causes directly instead of letting the government allocate it; they don't trust the government with that extra money any more than you do.
This is a well received economic theory, not a way to save face on taxes by promising to give away money in the future so that I don't have to pay taxes now (Zuck).
I already voluntarily pay more taxes than I need to. It's pretty easy to (legally) pay much less tax if you are running your own business.
Also, I and quite a few other people I know don't use GiftAid when giving to charity or buying things from charities (GiftAid basically lets the charity claim back the income tax that I've paid on that money) for the reason that the government is better placed to know what projects need money than I am. They are more likely to spend the money on 'unfashionable' things that don't trigger the same emotional response in people but are actually more effective uses of money.
