First, the price is a filter. People appling for $10 help and for $1000 help are very different. The author knows his readers should too: the books and videos are free and available to use for their sake – that's their own time.
The second reason of the high cost – is the experiment Alexander puts himself on every day: does not celebrate the birthdays, does not see the relatives, does not watch television and does not spend a third part of his live just eating and sleeping. He is always gathering the information, testing it finding solutions to any problems in life and works on himself. Therefore, this information is estimated expensive. There is a certain contingent of readers that require the attention of the author in person to their personas and angrily declares that Alexander is given a gift, and he is making money out of it. But it's not a gift. This information can be compared to the mushrooms in the forest. Mushrooms grow everywhere, and yes, they are free. But if you are sitting at home and watch TV, and Alexander is walking through the forest wet and hungry to collect this mushrooms, doesn't sleep at night and spins them into the jars, he can't give it away for free. Alas, the man himself has to go all this way Alexander did. So the man will know everything Alexander knows , and it will be absolutely free for him.
The third reason of the high cost - is how the reader treats the information. Author is often making online conferences with the different costs. It depends on the kind of information he gives. At the conferences people have to be more focused, so they are more likely to believe the information and take it serious. The higher the price – the better result they get.
