Actually, the only way I see a prospective entrepreneur "getting rich quick" is not by any sort of saturated system or method, but, rather, creating their own original venture that many people will have a use for. For instance, MySpace was one of the pioneers in social networking, but the founder of Facebook took that concept, improved on it, and made it vastly more addicting, thus netting billions of dollars in a few short years. The same can be said with Twitter, or sites like WordPress or Apache.org where an original concept was applied or an existing one improved on and marketed for money. That isn't to say that WordPress or Apache do this for much profit, but you should get the point.
Granted, it is very difficult to fabricate an original concept that hundreds of thousands of people may potentially get involved in and net you millions of dollars, but think about it. Those who did manage to do it are now the revolutionaries of the internet. No program or system that multiple people are investing time, money, and energy in is going to make you rich in a short period of time, it's the "the road less traveled" sort of scenario that will ever allow that sort of thing to happen, I think.
Brilliant points made. Think about youtube. I'm sure we all are daily visitors to the site, and probably all have difficulty remembering life, or at least the internet, before it. It's barely 8 years old, and has made countless millionaires and celebrities in it's wake.
That being said - you can still make plenty of money following others. It just won't be to the point you can swim in a vault of gold coins ala Scrooge McDuck in Duck Tales.
I'd also like to point out him diving into that fault of coins and swimming in it violated quite a few laws of physics - but it was a cartoon, so I'm likely over thinking it.
