Let me elaborate. ;-)

Yes, I have worked with the occasional stupid person over the past few decades, but I would say that genuinely stupid people comprised only maybe 1 out of 10 of all the people I have ever worked with. Most people are not stupid, in my opinion, although that's not to say that they don't have a few emotional hangups of one kind or another.

Let's put it this way. Really stupid people are actually rather rare, despite what movies, commercials, and TV shows would have you believe... ;-)

Stupid practices, laws, and social customs, however, are quite common...

What I am saying is that the public, in general, is rather poorly served by the pressures of the social conformity and the marketplace around them.
