Basically, although base intelligence/smartness perhaps has two parameters that make it? Effort and speed. Everyone can put in a bit more effort, but base speed may be baked in, unless one trains it, and max reachable base speed will depend from person to person. Hell if I know, we haven’t really created a definitive definition for intelligence yet.
Edit Addendum: As for what can be considered dumb or smart? I agree, lack of effort can be considered “dumb”. Though the word dumb is a bit broad. I guess we can say many people are, out of habit, “intellectually heedless”
Shit even Republican voters and Republicans “should” want minimum wage tied to rate of inflation. Why? Because it creates incentive for the Federal government in keeping inflation lower, keeping inflation lower being something that “supposedly” the average Republican voter wants.
