I have a friend (an african american) got his license 2 years ago and made base salary 70k a year as a first year driver and he gotta buy his own truck. All of them are independent contractors having much less protection in the legal system. A truck driver is stuck at 100k to 150k a year while a MBA has earning potential of more than 300k. Truck drivers doesn't get stock options. They gotta buy their own med insurance. You will be on the road 6 out of 7 days a week. What does it appealing to you??? Be happy with what you have, make the best out of it....
