(NewsNation) — As the cost of college skyrockets along with student loan debt, Gen Z is turning away from traditional four-year degrees and going into the trades, where lower costs of education can still lead to significant income.

It’s a boon for industries that have suffered shortages as more people in previous generations chose to go to four-year colleges, an option that offers diminishing returns as graduates struggle to find jobs while also paying off student loans.

Chris Cuomo brought on a “Dirty Jobs” host Mike Rowe for a special edition of [CUOMO] focused on elevating and encouraging blue-collar jobs. Watch the full episode here.

In contrast, many trades offer on-the-job training or shorter, less expensive programs and have more jobs available. These occupations may also be more difficult to replace with automation or AI than office jobs.

From health care to construction, here are how education costs and earnings, as reported by the Bureau of Labor Statistics, stack up for 16 trades.

Plumber

Plumber certification requirements vary by state, but training generally consists of either an apprenticeship that combines classroom work and hands-on education or a vocational program followed by an apprenticeship.

The mean wage for plumbers is $67,840 a year.

Pharmacy Technician

Certified pharmacy technicians typically attend a year-long training program and must pass an exam to gain certification. Programs may be online or in person, and the cost can be as low as $400 or up to $4,500.
