However, bitcoin does not guarantee equality in terms of wealth distribution. It can help people make money out of it by investing and such, but it cannot eliminate certain bracket and class which gets richer and richer each day. Remember, bitcoin is open to all and can be utilized by literally anyone. It just depends on how you will make the best out of what you have regardless of the amount.
I think an utopical equal society isn't achievable through bitcoin or through any other way, it's just an illusion impostors sell people to make their own political careers.
But I have no doubts bitcoin can decrease the barriers between the richest and poorest in the world, since these people have a genuine will to work and thrive in life. What happens today is that our national currencies are very devalued, as pointed on this thread, and our economies are broken. So only few groups who have access and influence with the government find ways to make their fortunes, while all the rest have to perish.
But bitcoin gives us the chance to reach further and find job and investments opportunities anywhere in the world without the necessity of leaving home, city or country.
Bitcoin has already changed the current financial system in some personal cases, even with the system against it. And I'm glad for it.
