I was sure until the end of this essay that the author was going to argue for governments to pay for or heavily subsidise a post-secondary education (as in fact they do in much of the developed world); all the arguments about an "educated population" seem to point in that direction.

So I was surprised that the conclusion was instead that employers should pay for the college education that they are benefitting from. Surprise: they already are. They pay your salary, from which you pay your college loans. It does mean that your take-home (post-loan-payment) pay is lower, but that's because you're still just a journeyman. Any arrangement where the employer pays more than a base salary means that inexperienced fresh-outs will be more expensive and thus even less desirable than now.
