so why don’t we get really good choices in politics?
Why is it a choice between Bad and Evil options in politics? Because really Good people don’t go for those jobs. And the few decent folks who are in there are not powerful enough to swing traditional voters, so idealists go for them, but not practical people (eg Bernie Sanders, Jeremy Corbyn).
No, really good people want their cushy private lives, they want to make good money, have a good time, maybe buy a nice place, build a business, settle on land or some other personal dream. They do not want to go toe to toe with evil in an arena it is well established. Until that changes, this is as good is it gets, and the eagle eye view is so honest in my eyes.
