There's many types. I sold Audi/Porsche and every now and then I'd sell a fancy car to a FedEx driver type that does long haul runs to other states (with a team driver next to him), and he'd be making $150k a year+. Not bad for 4 days a week work, and ability to live in a slightly lower cost area.
Truck drivers making $80k a year and home most nights is pretty common.
Well California automatically pays more than most of the country. And I believe FedEx has some Union drivers. And yes, just like the average software engineer salary isn't all that dang high, when we discuss the industry we tend to look at the most successful group we aspire to be in, not the burnouts that aren't that good at their job.
