One seventh of the US population has an IQ of 82 or lower.

The US military will not accept anyone that tests lower than a GCT Cat 4B, which has a bottom limit of 83.

Why? Not because they can't push a broom or stack boxes... but because they require more resources to supervise, deal with the aftermath of their mistakes, etc. than they can produce. They are literally useless. Incapable of contributing.

Your experience is the sort of "thinking" such people do when abstraction is involved.
