I've done some maths for LTW. If you were lucky enough for 88,573 people to sign up to the scheme under you, you would earn £44,000 ish a month. You would be at the top of a pyramid or downline. But for those people on layer 10 (59,049 of them) to have pyramids of their own of 10 layers so they can earn that much, there would have to be 1,743,392,200 in the whole pyramid with you at the top. Considering this scheme is just in Britain, that doesn't seem very likely to me.
Therefore, those projections of income are not achievable. Of course, we knew that, but I really felt like doing some sums tonight.
