I think for something to redistribute the wealth it has to be a system that benefits those it's meant to affect. Say the poor. Bitcoin is more or less equal opportunity. A choice, one can choose to invest if poor, and have made millions if it was done years ago, or one could be super rich and not invest and have gotten nothing from it.
One of the great things about bitcoin is that even if you have a lot of money and you can use that money to get bitcoin that does not mean that a poor person cannot get a lot of bitcoin too, the only thing you need is a good idea and start a small business in this space and if you cannot do that if you invest a few hundred dollars in a good and new coin you have the chance of making a lot of money as well, so the field is more fair compared to the real world.
