I think people are always underestimating the power of mentorship, and people are ready to learn, but they are not ready to actually allow people to help them. But is only when things become very bad that you will see people complaining about trading, but at the same time, fail to learn.
I don't think people are undermining the power of mentorship but I believe it's getting to extremely expensive recently. Mentorship aren't free or as cheap as they used to be. Presently you'll have to pay the money that you could have been using as your capital for the business you're receiving mentorship for. Instead of paying for that mentorship, it's cheaper to start the trading lessons for free on YouTube or any other channels that you can learn real trading for free. Don't ignore a free mentorship because you stand to benefits alot when the mentor is good at trading and teaching too. Mentorship should be the best way of learning how to trade because it eliminate the chances of you making fetal mistakes.
