Interesting view you have of unions...sounds exactly like the one espoused by Faux News. So, tell me: exactly how did the unions take the auto industry down? Did they decide, in a market that's growing increasingly cost and environmentally conscious to not build cars that met those criteria? Sounds like a management decision to me. When your total payroll costs are X amount, but the amount of your losses each year is almost 3X, you think there might be something else causing your losses? When the unions take over management of their people's benefits packages, thus reducing your overall operating costs for that facet of your business by about 80%, how exactly are they costing you more? Perhaps you believe the flawed "auto workers make $50/hour for polishing mirrors" meme?
But, on to the next topic: airline safety and unions...this is a new one, I have to be honest. But, as someone who has a couple of close friends who work for airlines, I was amused to find out, for example, that limiting the size and number of carry-ons was a push by the unions, not to mention exit lights (which the airline management decided was a useless waste of money). Pilots are looking to unionize because, frankly, they're worked like dogs with very little rest. Some have even fallen asleep on the job. Now it's easy to say "well, then, do go to work tired". Of course, when your only real option "don't go to work", it fails to pay the bills.
Finally, the teachers: are you saying the SOLE reason the educational system is a failure is due to the teachers? You're going to exclude government mandates, like the always favorite "No Child Left Behind" which was put in place specifically to make the educational system fail (I honestly admit I cannot find any other reason such a flawed pile of shit could have been passed)? You're going to exclude the fact that we don't have a single, unifying educational system, but one made up of 50 state systems, uncountable municipal systems and an overarching Federal system. In the right conjunctions, they don't contradict each other, or work against each other. Fortunately, those conjunctions aren't rare right now, but they are getting rarer (as in the case of the Texas school board's decision to cease teaching reality). Finally, what about parents? The #1 gauge of a child's long-term success in the school system has always been and continues to be, the parents...their involvement, their financial status, their marital status, etc...A child that has a parent at home to work with them every night doesn't need as fantastic a teacher during the day...but, so many folks want to be career-oriented first, family second, so the kids get the short shrift. But, hey, at least my folks TRY to make it to every soccer game, right?
It's easy to simply go with the flawed mentality that fits your mood. What is hard is doing the critical thinking and research it takes to be an informed member of society. It's apparent that you lack the ability to do the latter. Fortunately, it's never too late to learn. You should look into it.
