I am sure it is all well regulated and as far as I am aware the US President has a fixed Salary.

When one compares the salary of the US President and the salaries of certain US CEOs, COOs etc he is very poor ion comparison, perhaps the video you posted was more concerned with the 1% of stupendously high net worth individuals compared to the 20%+ who are dirt poor in the USA. I think perhaps you have mistaken priorities.
