I think Bitcoin will help us eliminate usury over the long term, because if we can make it the standard our system won't be founded on debt and usury. It will at least make fractional reserve banking less viable and thus stabilize the lending system to no longer unfairly favor those who know how to game it.
In the years since 1971, the loan amounts for home, auto, college, etc. has exploded, rendering savings untenable, especially because the depreciation inherent to fiat currency.
An appreciating currency will reduce the desire to lend it, and thus increase interest rates and decrease loan longevity, which will make the total value of loans to go down, and with it prices also, making savings much more viable.
