This is the most underrated aspect of Trump's presidency, and of the importance of not letting a Democrat into the White House. It is not just repealing economic regulations, $33B, and the effect on the economy, but also the rules, regulations, and administrative law decisions coming from the EEOC, Department of Education, Department of Labor, etc.. That is hidden to a lot of people, but it has a huge impact on secondary education, college campuses, the workplace, etc....
I'd rank it as the second most important power of the Presidency after the Supreme Court, and Trump has been absolutely aces in slowly turning that stuff around. It's wildly under-appreciated by some of his critics on the right.
