krellin, Lots of engineers are smarter than me, it's a tough field which requires (you guessed it) the skills which a study of the liberal arts develops. You can't do engineering without math. We need engineers and other professional and technical folks, although I suspect we have too many of some.
Your reliance on crutches of bad thinking, like the word "libtard" or your insinuation that I am a pauper and such fact has some relevance on the points that I make a.k.a. the ad hominem fallacy, plus the fact that you did indeed take some liberal arts courses, suggests you might be beyond the improvement of even America's best educators. But for the average individual, a better understanding of history, rhetoric, science, and so on (i.e. the liberal arts) will make them a more well-rounded citizen - crucial to the very existence of self-government - and I would say more professionally valuable. Almost everyone writes and communicates in their work, for example, and most people can only get better at that in a liberal arts curriculum.
jmo, money is important, sure, but it's a means to an end. You recognize that there's a larger purpose, and I applaud that. However, lots of people in technical fields seem to make the same mistake which you ascribe to liberal arts majors - a misunderstanding about what's a tool and what's the purpose. The study of the liberal arts best provides the skills and knowledge to understand what's important in life and how to navigate it, the same way that a good income makes it possible to get through life more easily. But neither is a goal in themselves except to the extent that they're enjoyable.
I find it impossible to believe that you don't see people even on this very website who need a more rigorous background in history, persuasive writing, critical thinking, and so on.
