I know a lot of people in their 30s and 40s who don't have a college degree. They make no less and have no fewer job offers because of it.

Go to school because you enjoy learning something(1), not for better job offers. In the technical realms nobody is going to care about that. It's more important to show that you can do good work.

(1) and honestly even if you want to go to school just because you're curious about a subject I'd recommend checking out MOOCs like Coursera and Udacity first.

Conversely, I know lots of people in their 30s and 40s who don't have a degree, clearly make a lot less and don't (and didn't when they were younger) have access to many, many job opportunities because of it.
