I'm not confused.

Your comment stated that college doesn't add much to a person's employability. (If you had wanted to be less obfuscatory, you could simply have said "a [HS] education is already adequate qualification for many jobs; college doesn't add much").

That was your claim. (I don't think your claim is correct of many OECD countries' colleges, but it was the claim you made.)

You then replied to J-Kuhn to say that they had misunderstood your comment by (mis)paraphrasing it as "Students attend college to become qualified to work."
