evidence: The Congressional Budget Office (CBO) finally released its long-awaited cost analysis of Democrats' Build Back Better Act (BBB) last Friday. [...] According to Biden and a relatively small band of left-wing economists devoted to saying whatever they must to help push the Build Back Better Act across the finish line, Democrats' plan to dramatically expand the IRS will result in enough revenue to offset their new spending. In October, President Biden even went so far as to say that the plan will have a "zero price tag on the debt." [...] This almost certainly will not happen. It is incredibly unlikely that numerous key provisions of the BBB will actually sunset according to the bill's terms, especially considering that President Biden and Democrats have repeatedly promised that the Build Back Better Act is meant to "rebuild the backbone of the country" and "set the United States on course to meet its climate goals, create millions of good-paying jobs, enable more Americans to join and remain in the labor force, and grow our economy from the bottom up and the middle out."
