Kiyosaki IS a charlatan and a fraud. He lied about having a Rich Dad, left behind all of those who propped him up in the beginning, and some of his advice is flagrantly illegal.

Not to mention, his interest is not in educating the masses, but in selling more books and courses.

I have no opinion either way about Dave Ramsey. I did do the snowball method to pay off all debt, without having heard of Dave Ramsey, but other than that, I personally disagree with his approach.
