I think that’s just another illustration of Kiyosaki’s oversimplification style of teaching. I think he’s not really as dense as he could be made out to be with some of his writings. Just take a look at the OP and this thread. If you take his definitions and his viewpoint too literally, it could cause a lot of problems, but if you come from the understanding that he’s just trying to drive home a point, I think it can be effective.
Whether or not it does more harm than good, I don’t know. But I definitely see a benefit to the way he presents a lot of things. His cashflow quandrant is obviously another example of something really simple…but it’s quite brilliant in part because of that simplicity and accessibility. He has certainly been effective in getting a lot of people to see the world through a different lens. In other words, he’s more of a key to a door, or a stepping stone…he’s not what’s on the other side.
