But often enough, conventional wisdom can be wrong, and that's the case with a college diploma and a high-paying career. The fact is, there are plenty of high-paying jobs that don't require a college degree or sometimes even a high school degree, and we have 25 good examples below to make that case.
Try these jobs on for size.
1. Brick Masons
Brick layers are in high demand as the U.S. economy expands, with annual average salaries around $51,000. You only need a high school education to get steady work as a brick mason.

Brick layers can work for a construction or landscaping firm, or start their own business.
2. Costume Attendants
Costume attendants can enjoy the footlights and glamour of stage and screen, and earn good money doing so. Annual average salaries are around $53,000, and more in large urban areas like New York City and Los Angeles, where demand is highest.

A career in the food services management sector is fast-paced and fun, and often, you get to bring the leftovers home with you.

4. Gas Station Operators
Gas station operators aren't in as high demand as they used to be, given the trend toward electric vehicles, but while figures vary, there are about 150,000 gas stations operating in the U.S., as of 2017.

Selling houses has become a popular career choice for the growing number of real estate agents in the U.S. - 1.3 million strong in 2017. The job requires a high school education, pays about $58,000 annually (or more, in high-income markets). Expect to know as much as possible about homes, property sites, real estate contracts, and general condition of sales. The more you know in the real estate market, the more houses you'll sell.
6. Boiler Makers
Professional boilermakers, who build, install, and repair boilers that contain liquids and gases only need a high school diploma or equivalent. Annual salary stands at about $62,000 and the only on-the-job training needed is an apprenticeship in the art of boiler making and maintenance.

The median annual wage for auto insurance appraisers is $63,000.

10. Casino Managers
Working as a professional casino gaming manager can be a pressure-packed line of work, as you're working with the public, and with the public's money on the line.

14. Claims Adjusters
An insurance claims adjuster can earn, on average, $64,900, and there's no need for a high-school degree (although a high school or college degree can help.) On the job training is minimal and employment growth projection through 2026 isn't exactly robust, at minus 1.4%.
15. Subway Operator
A subway operator can not only earn a decent wage, at an average of $66,420, but since most subway and streetcar operators work for the public sector (mostly in large urban areas) benefits can be ample, as well.

21. Elevator Installers and Repair Technicians
There's high demand for elevator installers and repair professionals - average salaries range at $80,000 annually.

22. Law Enforcement Detectives
Detectives and criminal investigators don't need a college degree to ply their trade, but it is a specialized line of work, requiring patience, diligence, keen intuition, and a bulldog mentality.

25. Air Traffic Controllers
Working in the air traffic control field can come with high levels of stress as it involves guiding aircraft loaded with people and cargo safely through the air and landing on the ground with no mishaps.
