You should read the whole thing, but Lance Mannion kills it (boldface mine):

People who love money don’t become teachers. People who do things because it will make them lots of money don’t become teachers. People who will become teachers because they might now and then win Andrew Cuomo’s proposed teacher lottery and pocket what only sounds like a lot of money are not people we want becoming teachers….

Teacher lotteries are premised on “excellent” teachers being as driven by money as lawyers and salesmen and too stupid to do the math.

As the kids used to say, read the whole thing.
