I think driving is looked down on but somebody with a high school diploma can make more than another guy that spent $100k on a college education.
That is a good point and true. But for it to be true the high school graduate must wait until he or she is 21 (23 with some companies), approach trucking as a business even if he or she is an employee, have a long term plan in mind and manage one's money well.
Note that completing the best or worst training is not on the list. If any truck driver wannabees are still reading this thread so deep into the head butting, I'd like them to know that trucking continues to be one for the few places where you can get free training (in return for a year or two of required service) and get to work fairly quickly.
Make no mistake. Some companies are better than others, and some border on being just plain evil, so be careful and do lots of research before committing yourself to what may turn out to be a nightmare trap.
Nevertheless, if you have no other way to pay for your Class A CDL training, trading some of your time and labor for that training can be a path of entry into a business in which dedicated people can still prosper and enjoy the work.
There are many indentured servitude horror stories out there, and it is also true that there are companies who have found CDL training obligations to be a profit center. Once they have your name on the contract, they don't care if you complete your one or two years of service. They don't care if you succeed as a truck driver. That is not their plan. Their plan is to make money off the training contract you signed.
Company training is an opportunity. Pay attention to the horror stories. People are not making them up. Also seek out company training success stories. Find and talk to drivers who have gone this route and done so to their benefit. Find out what they did to make the company training option work for them.
I drive a straight and entered the business with a Class B CDL and being only self-trained so I am not personally familiar with the Class A CDL path. But it would not surprise me a bit to learn that there are numerous people hauling expedited freight today who got their Class A CDL by following the company training path.
Perhaps some of them can share their experiences and tell us if they consider it a good path or not.
