I think we need to define wealth redistribution (WR) before we go much further. Is it WR to tax the public and use the money to pay for military programs of little or no use? Is it WR to tax people and use the money to pay for education? Is it WR to use taxes to keep an aristocratic class from developing and undermining democracy?
I'd also like to point out that wealth creation doesn't necessarily lead to prosperity either.
Wealth is created when an asset is moved from a low end user to a high end user. A person that uses a hammer only so that he can use the claw end to clean his ears is a lower end user than the person who is building a house with it. So the builder gives the ear cleaner money in exchange for the hammer, the ear cleaner then buys a box of Q-tips and keeps the balance, and the builder builds a house and sells it. Wealth is created by this transaction as assets are being used optimally.
From a basic theory perspective, a free market is the optimal vehicle for assets to get from low end users to high end users through transactions driven by personal self-interest. The builder needs a hammer, and the ear cleaner is better off with the Q-tips and a few bucks. This, expanded out, is the free-market wet dream. Everyone gets value and everyone wins from nothing but voluntary transactions.
However, reality is not basic theory. When you take one part human nature, one part human stupidity, and blend it in the blender of the imperfect thing that is reality, the free market both develops blind spots and other weird problems.
The result is that in some situations a government does a better job of moving an asset from a low end user to a high end user, or can prevent a transaction that in the short term benefits both parties at the expense of the society as a whole. (which is where I think you were going with your wealth/prosperity argument.) Things like the present, where businesses that are too big to be allowed to fail are allowed to profit from massively risky behavior. Same with profitable activites that poison the air or water of other people. (ETA: externalization of costs and so on).
While the free market generally does a better job, human failings add up in a way where a government is needed to step in for the greater good. This is obvious as to things like national security, and even to building infrastructure (rural electricification, etc.) that makes extra free market transactions possible.
Unfortunately, those that notice that the government is not the best tool somehow come to the conclusion that it is never the best tool and equate anyone that says it is in some circumstances with those that say it always is. This is where we get the intended slur that Obama is a commie.
