Suggesting that simple, direct, change of the variable that has direct linkage to pretty much all other parts of the system, will achieve some specific result, is almost certainly wrong.
In fact, pretty much every mechanism taught of how to effect change in large scale systems says not to do that.
In this case, this is pretty easy to see - As an example - If you could pull six figures teaching, everyone would want to teach, regardless of whether they should or not.
Solutions to this have obvious affects on other things
(IE increasing credential requirements, or performance reviews ...).
These in turn have effects on other parts of the system, ...
If you really think this is just simple, i'd suggest looking at https://en.wikipedia.org/wiki/Complex_system#Complexity_mana... and going from there.
