As a percentage, how many US colleges would you say are excluded from the opportunities provided by "rigorous course of study"? Would you say you could get this kind of rigorous study at any university? If not, how many (as a percentage of all undergrad colleges)? Is this scalable/sustainable for the entire population?

I don't know, and I don't think the answer is as relevant in this context as might be hoped. There are many known, admitted, and well-documented failings in and problems with the current tertiary educational system. Yet, it's perhaps possible that these are not repaired by stripping away some of the aspects that are of value.

The general need for a better approach might not be the same as a given different approach being better.
