Perks for tough jobs are necessary to keep those jobs filled. Hell, I'd be OK with waiving fees for military folks entirely.
You guys have it pretty good with the fees, though. Here in California, we just elected a super-majority of Democrats to state government, so they now have the power to implement anything they like. They are proposing to TRIPLE our vehicle fees. That will take me to about $350 for my 1996 Chevy K1500. The poor bastards with the big diesels are looking at $2,100 per year.
