Teacher shortage, especially in SPED is a huge problem.  But the band aid fix is subs and 89 day temporary hires taking their place regardless of if they are properly qualified.   I agree housing and finances is an issue but some times things that hsta fights for isn't just money, it's for more time to do the paper work or for PD, or for better funding for resources.   But the reality is that people do not go into the field because it is lucrative, they go into to it because it is a calling or a passion.  So the idea that money/housing dominates things is both a reality but also not necessarily what it's all about from the standpoint of teachers.  The other is that when the doe messes up then they put more on the plates of teachers to "correct the problem".  Better leadership, management and accountability up top might help also.
