Unfortunately, to get that kind of education, in my experience, one must pay a little more. Even then, that kind of experience isn't guaranteed.
The thing is though, that even "out there in the real world", if the educational experience doesn't live up to it's reputation, people vote with their feet.
The best schools and the best universities are that because they hold themselves to a higher standard, and the results often reinforce it.
There is a danger in that thought concerning perception as opposed to reality, but I'll leave it alone for the moment.
The "buffet of ideas" thought isn't a bad one. In my view, it's a perfectly lovely one, in fact... bearing in mind that any idea is going to be rigorously examined if it's to continue to be entertained and, finally, accepted if it has merit.
But underlying that, must first come investment.
Investment in the facility to entertain ideas.
Investment from the staff.
Investment from the participants.
In short, behavioural economics, I suppose, although I haven't studied the subject beyond a cursory examination.
Investment in the form of capital would have to come in there as well, but I have little information on how much that is in play, with regard to this site in particular.
With more regard to ideas themselves, new ideas are often seen as cockroaches, particularly when they find themselves up against accepted morality.
The first instinct is to squash them, or run for the insect spray.
If they get under the fridge, people give up and leave them alone. Out of sight, out of mind.
Most don't ever want to see a cockroach. Ugly, dirty little things.
Only a precious few will capture the cockroach, study it, and find out for themselves that a cockroach is actually quite a useful little creature, as subjectively ugly as it is.
But if those educational systems condone the suppression of entomology and openly disregard dissenting opinion under the auspice of not seeing why anyone would want to study talking trees, you have a problem.
Hrrmmmmm..... hoom.
