    America’s trucking industry employs roughly 3.5 million people, carries 10.6 billion tons of goods back and forth across the country per year, and brings in $738.9 billion in taxes annually. It is, in some way, a logistical (物流的) wonder.

Though America’s trucking industry may one day be replaced by new trains, or giant trucks piloted by AI systems, for now we need to deal with the system we have, instead of daydreaming about a new one. Truck driving used to be a desirable profession for Americans, but almost no one wants to be a truck driver anymore. The industry is already short of 50,000 tractor-trailer drivers, and that number could expand to 174,000 by 2026.

The solution is simple: raising drivers’ wages (薪水). While trucking is generally considered a high-quality blue-collar job, average pay for truckers is only around $42,000. That’s more than $10,000 below the average household income in America.

Bear in mind too, that the economically essential function served by the trucking industry creates a very tough quality of life for truckers themselves. Being far away from home for days or weeks at a time causes all sorts of personal issues. Therefore, drivers really deserve to be paid more.

The good news is that last week’s jobs report did show an increase in wages. In trucking specifically, compensation finally jumped 10 to 12 percent over the last year. It’s not enough, but it’s a step in the right direction.

And to encourage the American trucking industry, there are regulations too. A federal rule from 2004 limits truckers to driving 11 hours in any 14-hour period.

Of course, this rule was put in place to make truck driving a more humane (人道的), and less demanding industry. But it also lowered the amount of driving any trucker could do, increasing the number of drivers needed to cover the same number of routes. And it couldn’t avoid the long hours on the road, lonely nights in hotels, and etc. The effective way to fix the problem is obvious: If your industry can’t find enough workers, you need to pay them more.
