Actually, it could solve some economic problems we're currently facing. The only reason it doesn't yet is because it's not only still in its infancy, but adapting to the way Bitcoin works is way harder than we believe. We obviously cannot see the difficulty of it because we already know how to use it & how it works (or at least a part of us, BTCTalk members), but you can clearly see it as soon as you try to tell somebody who has never been in this market before about Bitcoin.

There's also another issue: Bitcoin will never become a national cryptocurrency. Decentralization will probably never happen, only an illusion of it projected by the future economic system. Bitcoin might not turn us into the financial freedom we deserve to live into, but the world is surely being changed by it as we speak.
