Teachers in Trinidaad and Tobago are agitating for higher pay - they've marched and stayed home from work. They absolutely need to be paid more, but the rationale that I've been hearing isn't quite kosher.
Yes, teachers have degrees and advanced degrees. Yes they need to be paid more. But they should not attempt to compare their salaries to those of contemporaries in other fields. I have multiple degrees, but I don't earn as much as a friend of mine who went to school with me - she's a lawyer. Ergo - she can charge $500/hour. If I wanted to make that much, I'd have become a lawyer too! Some fields pay more and some less. One chooses one's profession based on many factors - money is just one of them. To decide that the salary in the field that you chose (knowing it was not as well paid as others) now needs to be commensurate with other professions can't be supported.
