Florida and Texas are spending because they make life for educators utter hell and there are plenty of other good reasons no teacher wants to go there. Illinois may be a single counterexample, but this is akin to saying "if you watch Craigslist for a few weeks you can get an amazing deal on one car" - the plan does not scale, and if a non-trivial number of the people in the market for [a used car / a better education job] tried to go for that target it would instantly dry up as there aren't enough to go around by many orders of magnitude.
