I don't think they can, but this will not stop them from trying because it is politically inexpedient to tell the truth in these matters.
The mad rush to push every child toward college is partially responsible for the push that resulted in No Child Left Behind which ended up leaving MORE children behind, and most of them the strong, middle class kids with great potential who have been stymied by being taught to the test.
"Tracking" is viewed as an evil in education but it is ridiculous to believe or perpetuate the myth that all students can be turned into college material. They cannot, and should not! All that is doing is making BILLIONS for the post-secondary education market and strapping too many with untenable debt and no better life.
We need people who can fix cars, wire houses, build buildings, repair small equipment and manufacture robotic parts. We also need people to do simple labor like take out the trash, mow the grass, babysit the increasing elderly population and more. It's time to STOP pushing the pablum thay every kid in K-12 has the potential to be a Rhodes Scholar and start teaching kids to rise to their highest potential. Then as real adults we need to model behavior that shows respect for ALL working people in ALL occupations so that kids have a model to follow.
Lastly - this economic mess needs to be mitigated so that hard-working, honest folks who didn't end up working for a hedge fund on Wall Street can make enough of a living to buy a home, feed their family and take an occasional vacation.
