Boilerplate job/career options for young men thinking about attending vs not attending college...
1) Enlist in the military. pay is sub-par, but your living expenses are well taken care of. picking a job that has a civilian equivalent is clutch here.. eg combat medic, electrician, plumber, various IT-related fields.
2) Skilled trades - eg plumber, electrician, HVAC-related. These pay from 50k to 150k depending on what type of work you do. The "high end" for example being a new-construction electrician, working for themselves, making $75/hr with overtime. All these fields have high job security - plumbing, electricity, and HVAC are not a 'fad', and are likely to increase in demand over time.
3) Own a "low tech" business, the sort you might already work for if you are a teenager. Eg...landscaping. You can make $15/hr running a weed eater, or with a small investment and some people skills - you can pay other people $15/hr to run a weed eater, and you run the business. This is more difficult than it seems on the surface (management and people skills), but it is not something you need a college education to succeed at.
4) Specialty/niche fields...these are more difficult to break into if you don't know someone already. Some examples are mosquito spraying(for a city), [water] well digging, or roadside assistance for a larger contract(like cell phone roadside assistance, AAA, or dealer contracts). These are easier to break into if you already know someone who owns that type of business, who will show you the ropes so you know what you are getting into.
This isn't an exhaustive list by any means, but hopefully someone finds it stimulating enough to come up with some ideas about work options that do not involve a mountain of student debt.
