"Highest" level doesn't mean much these days.
I know plenty of people that have doctorates that cannot figure out common sense, day-to-day tasks.
Plus "university" these days is not like it was where they used to get you ready for doing for yourself.
Now that degrees are a dime-a-dozen, they are merely certificates showing MOST completed basic indoctrination and are ready to work for someone else.
Double doctorate and able to rebuild engines and transmissions and possess common sense & street smarts?
