Does he break out comparisons to an earlier era with data? No, it's just a handwave of "back in my day" and some Rand Paul-esque "I don't know what these people do, but they are obviously not needed".
Here's a radical idea: How about asking the students, you know, the ones PAYING the tuition, what they think? No no, too logical, better to campaign on "firing 9 / 10 and reducing tuition".
There isn't even a bit of the article where he talks about how much the average student spends on all of this "waste" as he claims it.
I mean, there might be massive waste and he might be right. But as written, this article has zero evidence, and I would say as the author is a lawyer you think that evidence would be an important facet of your argument.
