OD, your post is absurd. Almost nobody can tell you how a TV really works, much less make one. But they have no trouble choosing good TVs in a society with specialization of labor. Likewise, the market, with mostly 8th grade educations, will have no trouble sorting out which airplanes to buy and ride, even if very few people know how to build a safe airplane.
BTW, we currently have precious few people with more than an 8th grade education, despite all the diplomas and degrees many of them hold. So, your point makes no sense anyway. Where the market is free, the product is good. Where the market is manipulated, the product is bad and the cost is high. (And THAT sounds like the public schools again...)
