While the Trump administration argued that the tax cuts would pay for themselves with faster economic growth, other analyses from independent think tanks and economists have found that the growth effects from tax cuts would be relatively small and U.S. budget deficit would inevitably increase.

The Committee for a Responsible Federal Budget (CRFB) said in a recent analysis that the tax legislation could cost about two trillion to 2.2 trillion U.S. dollars in the next decade, pushing up U.S. public debt to between 98 percent and 100 percent of gross domestic product (GDP) by 2027, compared with 91 percent under current law.

The Republican tax bill has grown more unpopular in the past two months and few people believe it will provide relief for middle-class families, according to an NBC News/Wall Street Journal poll released Tuesday.

Overall, 41 percent of Americans in the poll said the tax plan was a bad idea, up from 35 percent in October, while less than one-quarter of people said the bill was a good idea.

The poll, conducted Dec. 13-15, also found that more than two-thirds of respondents said the tax bill was designed mostly to help corporations and the wealthy.
