Cons/repubs: you really should be concerned about the disparity of wealth
Why be concerned?
Why do we think the current economy is on the skids?
Government redistribution of wealth is not as good a system as a system of fair capitalism.
That's why wealth maldistribution is a bad thing.
Because if the capitalist system is designed (by laws) to advantage one class over all others (which is what we have now, folks, let's face it) then that system cannot efficiently get cash to the productive parts of society that actually could make the best use of it.
