1. It is almost always wrong to reach general conclusions from specific anecdotes.
2. It is very common to confuse a liberal arts education with job training. There may be considerable overlap, but they are not the same.
3. There are now at least four tiers of higher "education" institutions in the U.S. The first and second tiers have almost nothing in common with the fourth tier.
4. At all except the elite, private and public colleges and universities the effect of Johnson's "Great Society" was profound; even at the elite institutions the effect was significant. The change took place, for the most part, in the decade spanning the mid 1960's to the mid 1970's. Later, when colleges and universities experienced undesirable outcomes from these changes they did not reverse course, which would have been very costly, but instead introduced remedial measures in the hope of making the new educational paradigm work out. That has brought us to where we are today.
5. Common wisdom has it that college graduates earn much more and do much better in life than high school only graduates. This is a clear-cut case, supported by statistics, where the common wisdom is actually right! It may be, that in the future, these statistics will divide according to the type or tier of educational institution.
