While there are fly-by-night operations that do exactly as you say, life experience tells us that this does not define all. I would stop with this, but I will take the comment seriously.
I can tell you (and clearly those that buy the product month after month) that the product is good and often far better than anything on the market.
There are many market verticals with incredible barriers to entry. In fact, with our global economy, most markets are all but impossible to enter without millions in investment capitol. We have government regulation and crony capitalism to thank for that. If you look at what it actually took to start some of these companies you will see you are absolutely incorrect in your assumptions, despite some anecdotal evidence.
