Trading college for trade school may have sounded like bad advice ten years ago, but with 44.2 million Americans carrying student loan debt, trade careers are becoming more attractive to high school graduates.

And you can earn a great living in the trades. In fact, you can earn more than many jobs that require a degree.

If you're looking to start life without a mountain of debt and still earn a decent living, here are six of the highest-paying trade careers.

1. Construction Manager

Construction management is a multi-faceted job. You'll be responsible for overseeing deliveries of materials, equipment and tools, but you'll also be in charge of ensuring every project has the proper permits and licenses.

Construction management programs can help you gain the skills you need to handle all aspects of contracting. Some programs also include instruction on environmentally sustainable building and green energy sources.

Demand for construction managers is high and is expected to continue growing by 5% between 2014 and 2024.

Construction managers earn a great living, with the average salary being $99,510 in 2016.

2. Aircraft Mechanic

If you love to fix things and you love the aviation industry, a job as an aircraft mechanic may be a good fit for you.

Aircraft mechanics work on a variety of aircraft, from helicopters to jets and commercial airplanes. Jobs are available in both private and public sectors, and you may work in a variety of settings, including airfields and hangars.

To get your foot in the door, you need a high school diploma and an apprenticeship.

Plumbers are always in demand, and their job is not likely to be replaced by robots anytime soon.

Plumbers and pipe lining fitters are paid well, and no two work days are alike. While you may not need a college education to become a plumber, the field still requires quite a bit of training.

These professionals may provide service to homeowners (i.e. fixing leaking pipes), or they may help install the plumbing system when constructing a commercial building.
