Here's my theory for what it's worth.
Any idiot can start in carpet cleaning, I did. And you don't need too much money to get going. So there are very few barriers. It's a bit like double glazing sales recruitment, there's no qualifications required, no track record, just see who sinks and who swims.
So whilst loads start, very few finish. But.. the twist is if you make it in such a competitive field (because there's no bar to entry) you develop immense skills in marketing, selling and tenacity as well as a new network of other potential possibilties that will reward you far more for your skills.
Just imagine a chap who decides to build his own web site, then wonders what the hell SEO is, then he starts applying multi step selling to it, opt ins, multi media etc. Suddenly his CC firm is doing very well thank you but the by-product is a whole new raft of skills that can be applied to make £££ withot touching a wand.

That Red Carpet guy was obviously switch on, I bet his CC business didn't 'fail', he found something better.
