You shouldn’t get multiple attempts at important jobs

There are around 100 million people who are eligible to be president of the United States. Of them, there are only six who have demonstrably proven they are incapable of winning a presidential election.

You have significantly better odds of success if you select a random person through a lottery than allowing any of those six people to run again. They are the only people who have proven they can’t do it. A failed presidential candidate is by definition the least qualified person on earth to be president.

I am more qualified for this job than she is. You are more qualified than she is. 100 million people are more qualified than she is.

This also goes for other big positions, like CEOs of major companies and University Presidents. You get one. If you’re a CEO and good at it, there’s no reason for you to leave the company you’re at. If you’re bad at it, no one should ever allow you anywhere near that seat again because anyone else has a better chance of doing it well.
