> you can bet your bottom dollar that when HR is hiring at Purdue they take the ag science BS grads over the high school grads.And I bet that is true. The person who graduated with a BS in agriculture science is able to complete the BS in agriculture science for the same reason that they will do well in the work place. The fact that the person was selected by the school to enrol in a ag science program means that the person is already determined to be better suited to the workplace the someone of the average population. They were already the best hire before they even enrolled to study agriculture science.
I mean, if you handed a agriculture science BS to a homeless person with a drug addiction, I bet the high school graduate is going to start looking far more appealing in comparison. However, someone who is homeless with a drug addiction problem is going to be immediately escorted off college campus even if he tried to get a degree. The degree isn't the appealing part to employers. It's the type of person who is able to attain a degree.
> there is no practical reason to not hire a college graduate for almost any job nowadays because there are so many of them looking for work at any rate beyond part time minimum wage.
I am not sure what you mean. Only about 30% of the workforce have a college degree. Employers don't have the choice to hire college graduates, even if they wanted to. Although that you say that a large portion of that 30% are struggling to find work is fascinating and, as income is a result of supply and demand, supports that incomes are not rising with attainment.
> Even if their degree is wholly inappropriate for your job, and even if your job has no reason to expect a college degree, just the fact they have one means two things - A. they can put up with rote bullshit while having the choice not to for years, and B. they are almost always indebted and thus are going to be more loyal to the paycheck.
Which is all well and good, but the fact remains that the income bonus isn't showing up in the data. These people are making the same amount as they would have had they not gone to college. They are making more than the drug addicted homeless person, yes, but that is not because of school. They would still be making more than the drug addicted homeless person even without school. And the Bill Gates of the world would still be making more money than you even if school wasn't a thing. Income diversity across the population has been around as long as we have been able to measure income and it was never a result of who went to school and who didn't.
