Someone with 20-30 yrs of service making 100k+ is no problem at all. Many 22 yr old grads start their careers making that amount. For example, someone with a BSCS or BSEE or BS in ChemE can easily get $100K starting salary.
I would tend to agree. The highest ranked teachers in my township on the list have been teaching for quite a while (20+years). But also now remember - they are working 9 months out of the year.
The real problem in my district is the insane number of administrators. Vice-principals for every grade, vice-principals of guidance (which gives no real guidance) and every other sort of administrator you can think of. Totally out of control. It is reflected in the reserved parking spaces at the high schools. Utterly ridiculous.
