To be fair, police have to deal with a wider range of psychological issues than jobs in rescue. Not only are police exposed to most things that rescue jobs are exposed to, they also have to deal with domestic violence, hostage situations, exploitation of minors and other disadvantaged groups, threats from organized crime, and sometimes actually pulling the trigger themselves. Hell, just the fact that police officers have to enforce laws they might not personally agree with is a pretty big emotional strain. My naive intuition is that rescue jobs are far less in a grey area emotionally.
I'm not saying this to quibble about whose job is more important or serious. It's just that I would volunteer as a firefighter or an EMT in a second, but I would have to think very carefully about how working in law enforcement would affect me.
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.
