They are terrible jobs. Years ago I had a class B and drove dial-a-ride buses. All-in-all it wasn't a terrible job because I got frequent breaks between passengers and could get out of the truck on those breaks and hang out at a mall or get something to eat. My counterparts that drove the city buses had to stay in their seat for 8 hours driving in circles around town.

The other thing that people don't realize about those kind of jobs is, for men at least, they are very hard on your prostate. Sitting for such long periods can cause it to swell leading to prosatitus along with a whole host of other bad health effects. All that being said, our jobs were cake compared to long haulers. You would need to pay people $120-150k before you could get a consistent hiring pool.
