Mining in a "collective" as the OP suggests would, at best, yield a few percent more profit compared to mining in a standard pool. Since pooled mining produces only modest returns at best, there is no way anyone is going to get rich by following the OP's suggestion. My guess is that the OP doesn't really understand the economics of mining, and hasn't done realistic calculations. Basically the OP has just made an off the cuff remark that has no basis in reality.
