【多选题】Which of the following statements about the The Tax Cuts and Jobs Act (2017) in the US are correct?
A.
On December 22, 2017 the Tax Cuts and Jobs Act of 2017 was signed into law by President Donald Trump. Inside the final version of the bill was a repeal of the individual mandate in the Affordable Care Act, which required individuals and companies to get healthcare for themselves and their employees.
B.
It was this mandate which kept healthcare costs down under the PPACA by promoting cost sharing over a larger pool. Economists believe the repeal of the individual mandate will lead to higher premiums & lower enrollment in the current market though they don't agree with how much.
C.
In 2017 the new Republican healthcare bill known as the American Health Care Act was passed by the House of Representatives under President Donald Trump. Although the Affordable Care Act and the American Health Care Act both propose tax cuts in order to make insurance more affordable for Americans; however, each of these bills affected Americans in different ways.
D.
The people most affected by President Trump's plan are young people, individuals of a higher socioeconomic status, and people who live in urban areas.
