You know a lot of jobs require degrees in the field, right?
And college is important for making connections. If you aren't in the right field, you won't get anywhere near the right connections.
As an exercise you might want to find 3 jobs, just 3, that say "bachelor's degree in SPECIFIC DEGREE required." They are not all that common. You can find them in government sometimes, but even those will allow experience to substitute for degree. Which means that someone who's been working there for forever will be getting the job. Sometimes you can find jobs in labs that require a specific science degree. Engineering jobs often require a degree + an engineering license.
But you should try to find some, and link them here. They are incredibly rare. If you can find 3 I'd be surprised and give you mad interweb props. When I started out I was told all about these magical jobs I'd be fit for as soon as I got a bachelors, and I ended up cleaning houses.
EDIT: you should also note that few people end up at the top schools like Harvard or Stanford. Places where all these lucrative connections can actually be made. Also, if you are the type of person that is smart enough or wealthy enough to make it to one of those schools then you are going to be fine anyway.
