On September 6, 2017, local time, in Mandan, North Dakota, the United States, U.S. President Trump visited the Andeavor Refinery and delivered a speech on tax reform. The picture shows Trump kissing his daughter Ivanka during the speech.

Trump announced his tax reform goals on August 30, hoping to revive the U.S. real economy through tax reform. Trump emphasized the principles of tax reform in a meeting with members of Congress: "First, we must simplify the tax system as much as possible. The current tax system is very complicated, unfair, and difficult to understand; second, we must provide middle-class workers with more benefits." and reduce the tax burden on families; third, we must regain the lost competitive advantage. If the current tax system continues, the United States will be unattractive to businesses and therefore will not be able to create jobs. We cannot tolerate being higher than other countries. The tax rate is 60, and there are currently 4 trillion U.S. dollars overseas that cannot be returned due to tax issues. "This is not just tax reform. To put it simply, what we have to do is reduce taxes."

The United States. Tax laws are the most complex in the world. Trump said 90% of Americans need expert help filing their taxes. Today, the instructions for residents to file their taxes alone are 241 pages long, compared with just two pages in 1935. Complex and difficult-to-understand tax laws place a huge financial burden on residents and businesses. Citing data from research institutions, the White House said taxpayers currently spend up to 6 billion hours on tax compliance each year, with compliance costs as high as $262 billion. Simplifying tax laws, reducing compliance costs, and closing tax loopholes are the reform goals agreed by both the Republican and Democratic parties in the United States.

Some opponents believe that this reform idea is too naive, and it is a desperate assumption that companies will use the money to invest and increase jobs after reducing tax expenditures. Critics also cited data saying that although the highest corporate tax rate in the United States is 35, data from the Government Accountability Office show that from 2008 to 2012, the average effective tax rate for large companies was only 14, and In the 1960s, corporate tax revenue accounted for 3.7% of GDP, but in recent years it has dropped to 1.5%. In other words, the contribution of corporate tax to economic growth is declining.

I really don’t know how to evaluate it, because we don’t know much about it.
