It is true that some people have far more than others. In releasing the protocol openly, Satoshi allowed it to roam freely, and those that understood the potential it held either mined, or bought in early. It was the fairest and most organic way possible to present it to the world.

Over time, when the world is hyperbitcoinized, meaning we are living on a bitcoin standard, those that have more will naturally spend it into the economy.

Even though at a certain point one will no longer be able to buy it with fiat, people will get paid for their work in bitcoin. Being paid in truly sound money will allow us to have real savings that will not be debased over time by inflation

While there will always be those with more wealth and those with less, due to a vast number of factors, a bitcoin standard will make the membrane between wealth classes permeable, as Aleks Svetsi says. This will allow both upward and downward mobility to be far, far more fluid than it is today.

Having been born into, and swimming our whole lives in a fiat world, it is almost impossible to imagine, and fully grok the implications of having a money that cannot be debased or manipulated!
