Absolutely! So many people bemoan taking general Ed classes, but knowing the basics about economics, literature, science, art, math, history is valuable if you want to think critically about the world.
The issue isn't teaching, it's learning. I don't think it's at all obvious that being taught by college professors is the best way to learn that material.
That's not the online material I was referring to. Many universities have their course materials available for free online. Not to mention other online learning sites.
Sure if that is relevant to what your goals in life are. I chose to get an education that was tightly coupled with the outcome I wanted.
Also, knowing a little about a lot of things doesn’t preclude you from being an expert in your field.
