The idea that you're going to make any substantial money selling a crappy ebook or running 100-200 autoblogs is absurd. There are countless reasons for this including the fact that your business model can be copied by anyone with enough time and energy to do so. So you end up competing with third world marketers and it is an inevitable race to the bottom. If you can't offer something that there is demand for, you are just a cog in the internet wheel. Simple as that.
