Look if you read the bitcoin whitepaper you will not find any mentions to give money back to the people, or distributing wealth in a more fair manner, or anything like that. Bitcoin is not really a social project, and if bitcoin gets adopted, rich people have more money, so they can buy more. The distribution will remain the same, that will not change.

Bitcoin sets itself as a new payment system. It's as simple as that!
This new system is better than the traditional one, because it removes the middle man, it has a limit cap supply, and it's decentralized. This alone, makes it more efficient than the current one, and stops banking for having the control over your finances through debt.

Bitcoin was not made for the poor to get rich, and the rich to lose their money. Bitcoin was created so that a better payment system exists in our world.
