I would say the ‘industry’ is still useless because almost all of the personal finance/investing information most people need could be summed up on a 1 page PDF.

If you are extremely wealthy, have extreme or complex debt, or are looking for the best way to take on debt, then maybe professional help could make financial sense.

Also, authors don’t usually pick their headlines. The point of the GQ article is that inequality/poverty are primarily systemic issues rather than individual failures.
