The problem with insisting on roundness, which has been a focus of the education system for years, is that it generates tons of generic shapeless people who specialise in nothing and find themselves unable to obtain the best, high paying jobs.
In my family, myself and my brother have been successful by focusing on one or two skills and honing them. That was made much harder by the education system, which fought us the whole way, because it sees specialisation as some sort of problem when it is in fact the solution. In my brother's case the school tried to insist he went to university. He didn't, as he knew full well what he wanted to do and reckoned, correctly, he would do better without being a student. In my case the university insisted that I take non-CS classes despite that I was paying them for a CS course. The classes were interesting, but marked arbitrarily (i.e. one essay at the end and who knows how it's evaluated?). I nearly got kicked out of CS because of a single essay written on archaeology!
As I go through life, I constantly encounter people who thought they were "learning how to learn" or "learning how to think" when they went to university, only to discover after graduation that they had no particular skills and were seem as essentially worthless by the job market. It's tremendously depressing for them and creates constant, lifelong insecurity.
Critical thinking abilities are something you want on top but are not a substitute for actual, hard skills. And they are certainly not something a university can teach - please. All the stats and studies show that universities are incredibly ideologically homogenous and rapidly stamp out any political thought that deviates from their left wing consensus. Universities teach people that thinking and disagreement are dangerous, that opinions are "triggering", and speaking out loud leads to exclusion. They're the last place on earth I'd expect critical thinking skills to emerge unscathed.
