The macroeconomics differs from the individual economy, and therefore the solutions that are followed for individuals differ from the macroeconomic solutions.
Bitcoin will help individuals increase their wealth, not governments (this may happen as part of a comprehensive plan, but Bitcoin alone will not do this).
Bitcoin alone will not be able to solve all of our economic problems in a country however it would be more of a domino effect. Once the investors of bitcoin get wealthy and they start actively participating in the economy this will result in an increase and positive activity of the overall economic scene.
This could then stimulate the economy because we know increased economic activity is a good thing so one thing will lead to another.
