That is a very narrow solution space you are considering. I can think of a dozen non-violent proposals which would involve nothing more than fiscal policy changes. For example: flat tax and basic income for all, such that there is no special treatment of corporations over individual entities. No tax breaks, no loopholes.
This would work best if implemented with direct democracy and a program of lean government held liable to be fully transparent on all spending.
A blogger who goes slightly more in depth with a proposal of this idea can be found here: http://www.naturalfinance.net/2013/04/improving-economy-by-e...
Of course the currently vested interests would fight this to the grave, but there is a point at which the people will no longer suffer the reign of Feudal lords (I predict that to be about 40% unemployment, or 70% youth unemployment).
