There are several ways trucking could be badly broken but still consistent with your statements: a) Say today, company X sells a thing for $100, of which $15 covers shipping cost, $15 is profit and $70 is what they paid their middleman for the thing. Suppose further that shipping cost could be reduced to $11 just by properly managing trucking, increasing the profit margin by 27%. These are of course made-up numbers, but just because a business is successful doesn't mean there are no inefficiencies left. b) It is well known that certain jobs take a huge toll on the people doing these jobs, causing early burnout, physical and/or mental health problems up to and including suicide, etc. E.g. drone pilots, people working with social media illegal content filtering have been covered in the media recently. If trucking causes lots of health issues, it's not just "badly broken" in the human compasdion sense, it also leads directly to reduced national economic output (with a 2x multiplier, you're taking away a taxpayer and adding an additional user of Medicaid/whatever).
