Another bottom line is that not all CEOs are good. There are good CEOs; there are bad CEOs; and then there are so-so CEOs, just like any other profession. I have worked for some good CEOs, some bad CEOs, and then so-so CEOs. None of them, I thought, would make a good POTUS.
That Trump having been a CEO doesn't necessarily qualify him to be a good president. The experience certainly helps, I don't deny that. However, people in other professions can claim the same thing. Trump as a CEO often failed miserably, unless not paying tax for 10 years or bankrupting companies 4 times counts as a qualification for being a good CEO, ergo the presidency. Can you imagine what would happen if Trump takes the USA to a bankruptcy 4 times?
