Agreed. This became an issue in Wisconsin where teachers and superintendents were double dipping and illegally arranging their succession to their own job. It is a big time cost a.d a political issue especially when government os no longer affordable.
And a lot of those Wisconsin retirees move to states that don’t have state income tax [like Texas].
It really is up to state and local citizens to sort this out.
Remember the mess in Bell, California [one of the more infamous CA messes]?
