I don't know what believing has to do with markets.
"one has to believe in the power of the market"
Markets have power whether you believe in them or not. Markets have the power to do good or evil. Unrestrained markets do more evil than good. Or maybe put another way, unrestrained markets aggregate more good to a smaller number of individuals to the detriment of the rest.
To avoid imbalance we must constantly be redistributing power from the stronger to the weaker. While it might seem unfair it creates a greater good. Ideally the stronger would use their strength to help the weaker and no intervention would be needed. Sadly this is not happening enough so some sort of intervention is needed.
I think breaking up big companies and taxing the wealth of the rich could be enough to restore balance but the effort can't be half hearted. It must be robust and affirmative, maybe even at the risk of being a little overboard until we see its effectiveness.
This solution is currently out of reach. The rich have captured all the levers of power and can't be forced to let them go. They will do what they want and that will not be breaking up their companies and increasing their tax payments. If they wanted to do that they could have at any time. They are actually forcing things in the other direction while they smile and explain how they know what is best.
