Probably one of the few bosses I've had I'll say nice things about.
No surprise, given what we've seen of your character.
Of all the bosses I've had, I can think of only one that I'd say anything bad about.
I do not think it is the case that you've mostly had bad bosses, while I've mostly had good bosses.
It isn't your bosses that have been bad people; it's you.
It isn't my bosses that have been good people; it's me. *
Our respective characters color how we interact with other people, how we perceive other people; and our attitudes toward our jobs and our bosses and our colleagues.

* That's not to say that my bosses haven't been good people. I'm pretty sure most of them have been. I'm about equally sure that if you'd worked under any of them, your attitude would have caused you to have nothing good to say about them, just as with the bosses that you have had. And if we'd worked together on an project, I have little doubt that I'd be the one who ended up having to clean up all the messes and screw ups on your part, stemming from your laziness, bad attitude, and general incompetence.
