Add to that that the quality of math learning outcomes and math learning in K-12 has gone WAY down. I point this squarely at 2 factors - No child left behind and the rejection of the common core because parents no lnoger felthtey understood the math their kids were learning. (and teachers did not understand math well enough to teach it well as a conceptual matter).
Even if they are getting the grades and even getting the test scores, they increasingly undersstand very little. They are not prepared for understnading they are prepared for question answering. Even in advnaced classes I see students actively reject learning and understanding for just answering - answering is the point they have learned. Right answers are the point, the only point.
A colleague and I were recently talking about what they see their middle nad high schoolers being taught in math classes. They termed it 'calculation as a defense against analysis'
SATs might help some but they aren't the problem they are a stop gap. K-12 (and by extension college) have so heavily sought to (poorly) quantify every aspect of experience to evalute people that they have stripped any meaning from the process. The problem is nothing has useful predictive value anymore in a process that is oversaturated by a 115% increase in the number of decisions an admissions office has to make. Its a math problem more than a cultural or standards problem.
