This Washington Post analysis of the Republican tax bill gives an exceptional view of the bill's impact and provisions. This is the first major change to the tax laws since 1986. The size of the bill is $1.5 trillion, with the Joint Committe on Taxation projection that the bill will increase tax revenues over a decade by $500 billion, meaning that it will cost $1 trillion being added to the deficit.

What the bill does:

1. It offers a permanent tax cut to corporations by reducing the corporate tax rate to 21 percent from 35 percent. Industries benefiting the most are mining, real estate, technology, manufacturing.

2. The individual tax cuts expire in 2025. They are skewed to disproportionately help highest income Americans, much less lower income Americans and much more highest income Americans compared to high income Americans. In this sense it is skewed in a an unusual way to the highest earning Americans- a sort of Trump effect in place. The top 1% get a tax break of $51,140 in 2019, middle income people earning about $100,000 get about $1000 a year in 2019, tax payers earning around $50,000 about $380, and those earning less than $25,000 about $60 a year in 2019. Taxpayers earning about 150,000 get about $2000 a year tax cut. (Tax Policy Center)

3. The basic assumption is that tax cuts are revenue neutral if there is economic growth and most of that growth comes from corporations investing in growth. The problem as Greg Ip points out in the Wall Street Journal is that countries trying thsi approach in the past such as Britain have not seen such growth materialize. Corporate profits are the highest in 15 years as percentage of GDP, according to Vanguard founder Bogle, and are now 20% of GDP compared 11% in 1980. If corporations did not invest with this level of profits how much additional investment is going to happen, ask critics, especially as demand drives growth and wages are not boosted under this plan. 

4.  Because the bill's changes to current law makes it likely that 13 million less Americans will be insured over a decade- from fewer people signing up for Medicaid and on exchanges for Affordable Care Act- it will hurt lower income Americans. Skewing at both ends of the income spectrum of this type is rare in American history particularly in the twentieth century after the Depression of the 1930's, and poses risks for social cohesion, making it unpopular with most Americans. A CBS News poll taken Dec 3-5 shows 53% of all Americans opposed, only 35% support the tax bill just passed in Congress. 

5. Then why did Republicans do this? Republicans needed a legislative success after failure to repeal the Obama Affordable Care law. This pressure led to passage with Republicans probably aware that this is temporary tax reform requiring a real effort by both parties working together after the midterm elections in 2018 and as the presidential election approaches in 2019.
