Because you’re too stupid for independent thought hence your career as a janitor.
I don't agree with much of what Prime says, but what does his being a janitor have to do with anything? I don't think anyone who works (or worked) for a living should be ashamed of what they do. One of the things that helped shape my treatment of others was my old boss (back when I had one), many years ago, who knew the name of the person who emptied his office trash. Treated that person no differently than corporate CEOs. That's the way it should be.
And if you actually think about it, it's blue-collar workers who are responsible for much of what makes our society work. We don't appreciate those things until the toilet isn't working, or the sink is clogged, or there is a pothole, or a light will not work, etc.
I know I'm not going to stop you from ragging on what he or anyone else did or didn't do for a living, but I'm just putting it out there that I don't look down on anyone based on their job.
Not calling you this, but we have a saying here about people who think they are superior: high maka maka.
