No, the whole point is "not much as changed". The narrative that one could pay their way through all of college is one that likely never really existed for a broad enough population outside of a brief unreproducible period after WW2 where the entire world was in ruins and the US was the sole supplier of all goods & services globally.
I can't validate the numbers but that would make your claim from earlier highly misleading:
> It's a little harder to pay for college on a teenage wage than it may have been 35 years ago, but not that much harder.
That's technically correct in the sense that it was already almost impossible back then and only got slightly more impossible today.
