Is the Internet realy helping people to make big cash legitimately and how

This days there are alot programs on the internet advertising one programs or the other asking people to join. Some ask for money to join theirs while some don’t.From chatting i was introduced to so many programs on the internet that i became confuse, but at a time i stop going to the cyber cafe though not because of the confusion but for some personal reasons, now that i am back it seem that the whole thing has increase.when i started going to the net some years back what i enjoy then is making friends on line, even planing on how to go for a trip, but latter didn’t work out.Among my friends one of them just start buying houses. How is this big money been made on the internet. I am not ignorant of the fraud stars(scam) on the internet, but i am talking about legitimate money on the internet.
