While teaching is supposed to be about giving kids the best possible start in life and while it's hard to think of more critically important influences on a young mind's development, the testing industrial complex and the lobbying juggernaut that it pays for can and will go out of its way to make you feel as precarious as possible and strip you of as many opportunities to actually inspire students as it can in favor of more testing and more test preparation while paying you less to do more and to pay for more out of pocket.
I don't regret teaching, but at present, I'm in no rush to return to it.
