It's not that they're 'so great' it's just that they are usually less business savvy and doing less 'jockeying for position'. They tend to not be in it for the money as much as they're in for the challenge which makes it relatively easy to take advantage of them. (Been there, done that, have several t-shirts to go with it and I promise it won't happen again but if I had known 20 years ago what I know now... never mind, hindsight is always perfect.)
