So, according to those so afraid of his statement, Plessy v. Ferguson should still be the law, there should be no child labor laws or minimum wage laws, because that was well established precedent?

Yes, Plessy should still be the ruling precedent. At least it was argued soundly, unlike Brown, which reversed it.

It wasn't until Roosevelt stacked the Court with his "Progressive" fellow travelers that child labor and minimum wage precedents were revisited, and generally overruled by drastic extension of the Commerce Clause. That's not exactly what I'd call progress.
