So you're a socialist. You'd like everyone to be the same and have the same incentive to mine, receive the same rewards and all that. What's next? We'll equalize bitcoin and make all the big wallets contribute to small wallets?
It's completely normal for companies to seek better and faster miners. Competition is good as it fuels innovation and paying more to those who are the best, the fastest, the most innovative, rewards them. If you give everybody the same reward, you'll reward laziness. Why would I rent a warehouse to have enough miners to compete for block rewards if I can get a USB asic miner?
