Does this not seem strange to anyone else?
The whole industry is feeding off a need to make money and then teaching them to sell information about how to make money.
If this was done on the street it would look like this and you would probably get arrested; You walk up to a person on the street and you say, "Give me $10 and I will teach you how to get people to give you $10". They give you $10 and you tell them, "Go up to other people and tell them you will teach them how to get people to give you $10, if they give you $10". This goes on and on but nothing gets produced. Of course a veneer of legitimacy is added if you sell them a video on a CD on how to get people to give you $10. But it's no different.
