Ripple is a get rich quick scheme for it's founders.
No one goes into business hoping to get poor

But seriously, let's set aside emotion for just one moment. If Ripple delivers on all its promises and becomes the world-wide payment system that frees individuals from the traditional financial system, is it so bad that the founders get enriched?
If you truly do believe that everyone is going to use Ripple and that XRPs are going to skyrocket in value, nothing is stopping you from participating - you can buy XRP in bulk right now from Bitstamp (that's what I've done). Seems pretty fair to me.
It's how they would be getting rich not if.
