But, it's NOT A CALLING. It's a profession. Like all professions, quality is most often the result of price. The rule of relative value applies. Go to the Dollar Store and you'll get Dollar Store items. A new teacher in her first year of teaching--probably saddled with 40k in debt--earns $33,407.95 per year before taxes. It doesn't take a major in math to see why there isn't an over-abundance of teachers lining up to join the profession.
There are, of course, exceptions to the rule of value. Occasionally, we buy cheap and get high quality. That cheap couch held together for ten years through two children. The very premise of a 50% off sale implies additional value. There will be some teachers, like me, that teach for the love of it, for the calling deep within us. But, how many are there? We need somewhere in the order of 7 million teachers to teach the 77 million students in the United States.
Am I complaining that I don't earn enough? No. But teaching shouldn't be martyrdom, and no initiative to hold us 'accountable' will ever actually do so unless we start asking what kind of people we want to pay to raise our children.
