You don't really learn how to learn in a masters or undergraduate. You learn how to consume information, but not how to research new things, validate those and defend it to others in a rigorous way.
Whether it's worth the investment depends on ones goals in life.
If undergrad doesn't teach you how to learn at at least some level, that probably makes me question some of the value in getting an undergrad degree at all as that's one of the arguments for going through undergrad. I won't argue that a PhD isn't something of a next level but obviously there's a big cost involved, especially if PhD-type research isn't something you'll be doing.
