In my opinion, a college education (a real one) is still very much needed, in order to be a good citizen

if nothing else! But, such a thing almost no longer exists! What is "out there" there is a "watered down pseudo-education!" bureaucracy for the most part (see
Dumbing of America, and Carl Sagan's comments on "what used to be taught in colleges as rhetoric and analysis" in his
Varieties of Scientific Experienc) and way too expensive.
For "real education value/content", I strongly recommend you consider good community colleges for the first 2 - 3 years for the lower so-called "basic courses" (they are usually tought better there and are usually also used to weed out students

(so are taught even worse) in the so-called "higher univeristies" [a double bad whammy

] ), and then transfer your kids to an "affiliated" larger state school for the final degree!
In the meantime, watch your public colleges funding practices. What I see is that it's mostly a "government employees employment rice bowel", more than an
education system. Fight them!! Look at their real costs! Look at what they are giving your kids (e.g. football games and stadia
vs calculus?),
etc., ad infinitum. And, kill this "job security "college tenure " nonsense. If it ever was a political protection system for "academic freedom", those days are long gone, now it's a retirement-in-place-system for them. We get fired, why don't they?!
And finally, really decide what you want your kids to have, an education or an education for a career (and there's a big difference!) and how well is your publicly financed "forced education" primary and secondary system preparing them for whichever you choose.
Lastly, when it gets down to the wire, there are bunches of small scholarships that usually go begging. It takes time to find and file for them, but I know many students who funded their whole education that way.
Finally, move to a "good education" state. My state is awful, and their college degrees are both jokes, and "consolation prizes for existence" at best!

Hope this helps and is not too polemical!
