Every action has a reaction, while redistributing wealth seems like it would create a utopian world there are consequences and problems it would also create. These billions of dollars aren't simply sitting around in bank accounts doing nothing, they're being invested in companies which are (should be) providing some form of value to the world thus increasing the wealth of the world as a whole. If that money was taken and given to those less well off it could be squandered and then we're in a worse off position than now.
I'm not saying it's a bad idea, it seems fantastic, but there are always consequences and the reason we have capitalism is because so far it's proven itself as the best method of improving the wealth of everyone (through technology and cheaper goods.

That's not the reason we have capitalism, since we, generally, don't -- the places that had the system for which the label "capitalism" was created have all since adopted a substantial portion of the redistributive program of some of that systems most strident opponents (such as Marx and Engels) to create the modern dominant "mixed economy", for the precise reason that capitalism was an incredibly bad system and improving conditions for anyone but a very narrow class.
And when we do take steps back toward capitalism, we see that what aggregate gains there are get more narrowly concentrated, and the system gets worse at "improving the wealth of everyone".
