Ok, I ticked 20+. I've been learning for nearly 56 years. Degrees tend to make people *******s, they feel high and mighty. EIQ is much better that IQ. If you feel you never learn anything new everyday, can I suggest you're more observant to your surroundings etc..
It seems you absolve Ivy League guys like Trump and DeSantis of any need to display such skill, given their bombastic style of rhetoric. Or is that you see no need or rather no equivalency regarding political speech versus plain speech, conversation, or whatever it is this style of which you speak that you clearly do not hold politicians you endorse to account for?
I'm not sure how you managed to drag politics into it but I don't much like anyone who has an ego that hinders their ability to effectively communicate. Do you like being talked down to by left wing politicians?
By choosing "16 years" I assume the OP meant a 4-year Bachelor's Degree, plus high school, of course. Anyway, that's what I got and it served me very well.
