The US and most of the world's free market countries are actually highly regulated markets where supply and demand are strongly influenced by government influence. As for this particular case, truck driving is a crappy job, with its long term prospects darkened by self driving technology, and equal paying professional jobs in decent supply. If you're motivated enough to be a professional, you can usually find a better career. And there's a fairly hard cap on how much long haul trucker drivers can be paid before rail becomes more economic.
