The idea of a businessperson being able to lead a country is laughable. Countries don't operate like businesses. Countries HAVE to arrange priorities differently, while every single business needs to make a profit. Profit is NOT on a country's list of priorities anywhere.
A democracy like the US should be paving the way for the success of all its citizens, not just the richest. The billionaires have sucked dry most people's ability to prosper by valuing their own efforts several hundred times more than the efforts of the average person. None of the businessmen who've been POTUS have done anything spectacular for the country. Bush II took a balanced budget and a surplus (federal deficit erased) and left the country with US$3.293T (Trillion) in deficits, and gave away our ability to negotiate drug prices with Big Pharma. TFG was twice as bad in half the time.
You may love them, but billionaires and businesspeople are NOT out to help others, and that should be the key asset of any politician. Public servants aren't splashy and entertaining, but they also give a shit about everyday people, unlike the billionaires who exploit them for profit. Public servants aren't taught to Deny, Defend, Depose.
