My thought on UBI are...that it's very good idea. But like every other idea, it has good and bad features. UBI would somehow help to get lot of people to get on their feet. There would be more work, higher velocity of currency, more healthy people... But on the other side, financial unstability on the markets would be even more severe and VIX would always be extremly high. Currency would lose its value even faster (unless governments would do big cuts on other type of spendings....)
