Trucking is much different than it was only a few years ago. Restrictive regulations weed out what was anticipated as the dangerous truck drivers, but in the process, some good truck drivers can't get a commercial license, and their replacements may only have youth, and truck driving school credentials as their qualifications. With less drivers than needed, the only carrot for recruiting is more money, which increases costs, and the costs are passed on to the consumer.
I don't know where this will end, but we're all paying with higher prices. With a less mobile society demanding delivery to their front door, the prices are guaranteed to become higher. Those with a tight budget, or fixed income, will find meeting their monthly costs increasingly more difficult. Increasing fuel costs only exacerbate the problem, and there doesn't seem to be any relief in sight.
One other thing: Those that think a highly regulated, school trained truck driver is better might want to look at the results of these actions. Experience doesn't arrive with a piece of paper, and with treacherous congestion in urban areas, the inexperience leads to traffic problems, oppressive harassment by government entities, and the loss of good drivers that had enough. Even younger drivers don't want the constant headaches, and some couldn't be coerced back into the trade with exorbitant wages.
