While I don't accept that teacher poensions are as large a problem as you accept, I would argue if that is the problem, address that problem. yes, there is enough blame to go around, but so far the solutions have been to hurt not only teachers, but children, as classes will likely be larger, less money for them, as the system hasn't been touched, and nothing done to spend smarter, not more.
Now, while I can't say neither party cares about children, I can say they respond more to pressure from special intest groups than to the actual issues. This leaves business and unions dong more and getting more than children are. While unions are no more evil than business leaders, harming us not one bit more, thus no more deserving of anyone's rage than business, the fact is our leaders should be above both, and geared more toward problem solving. What I argue here is about us, what do we value? If we value education and children, we should not accept these blind, untarget cuts and should demand more, demand a plan.
If you want to run around demonizing liberals, all the while not seeing how easily you can be demonized by your support of business, I can't stop you. But do try to see what I'm actually arguing.
