You need to learn the history of price controls in the US. Trucking was (some say due to the power, at least at the time, of unions) a highly regulated industry. Those regulations basically turned the trucking industry into something akin to OPEC - a cartel. Price controls, barriers to entry, etc., etc., etc. It changed in the early 80's (in the 70's for other areas of transportation like rail and air) when the US government started to dismantle alot of the price controls and entry barriers. It's not that "someone" lowered truckers' wages/salaries due to "greed" - it's that their wages/pay was artificially high due to regulations that in essence restricted competition, and once the barriers to competition were removed, along came more truckers that bid the price of their service down. Now, if you want to paint it as "greed" - fair enough. Truckers were greedy, once the "rules" that were in essence limiting competition were removed - the shoe was on the other foot. I get it, it's "nice" to think about "this" or "that" group of people all making 6 figures, but let's face it - if you think inflation is a problem now, it'd be worse if truckers were all making 6 figures. And well, if you like cartels, so be it - but that just means we all pay more (whether that cartel is in diamonds, oil, taxi's, whatever).
