Unless I'm mistaken, and I don't think I am, my school district finds itself in the position of being contractually obligated to fund annual above-inflation salary increases forever.*
And since raises are figured as a percentage of current salary (I think - must fact-check), the 'miracle of compounding' is in play as well.
What's strange about this state of affairs is that:
a) smart, capable people (past school boards) created this situation without understanding that they were creating it
b) smart, capable people (voters) supported the creation of this situation without understanding what was being created
c) virtually no one, today, understands what the situation actually is
I don't understand it well myself, and I know only one person who does. (That would be the person who explained it to me.)
I'm wondering whether there's research on people's ability to comprehend trend lines over the long term. I'm sure there is.
* Well, forever assuming the Fed continues to target 2% inflation.
