By Dom Galeon for Futurism - The new study based its forecasts on three basic income scenarios. According to the first of these, if adults are given $1,000 every month, the U.S. economy could grow by 12.56 percent after an eight-year implementation. With current GDP pegged at $19.8 trillion by the Congressional Budget Office, this translates to a total growth of $2.48 trillion. In the second and third scenarios, a monthly UBI of $500 and $250 could lead to a GDP growth of 6.5 percent and 0.79 percent, respectively. It’s also worth noting that the report used an economic model that assumed that growth is constrained due to low household incomes, which the researchers note is debatable. Proponents of UBI now include experts from various fields, including some of the tech industry’s most prominent figures and entrepreneurs, as well as some of the world’s leading economists. Yet, just like any radical idea, UBI isn’t without its skeptics, and the biggest source of concern for these critics is funding. Just how would a government pay for a UBI program? An obvious answer would be through taxes, but according to the Roosevelt report, this set-up would essentially be pointless for the economy: “When paying for the policy by increasing taxes on households rather than paying for the policy with debt, the policy is not expansionary. In effect, it is giving to households with one hand what it is taking away with the other. There is no net effect.”
