True, but is that a problem with police salaries, or with military ones? I have a number of acquaintances in the military, many of whom have served multiple tours of duty in Iraq and Afghanistan, and as a taxpayer and (putative) beneficiary of their service, I'm personally embarrassed by how little they get paid.
They get the population median income. Without having to have acquired any skills before joining, all training and living costs are paid for after enlistement. Base pay is still far higher than minimum wage work. I'd say the problem in this specific context is undeniably CHP salaries being artificially super inflated above the national median income in a market inefficient manner that does not reflect supply of people capable of performing the work.
Not nearly as much as those serving in the military whose salary is vastly less (closer to the population median income).
