Except your implication that the rich get richer and the poor get poorer is stupid as

. In a modern economy while the rich get richer they usually do it by creating wealth.
Imagine it like this- A pie is on the table with nine slices on it that are all the same size. Now imagine a CEO comes to the table with four slices and adds them to the pie. So now the pie has 13 slices. Mr. CEO keeps two of those slices. So essentially by his actions he added two pieces to the pie, allowing others to grab more pie.
Capitalism isn't some "system" we follow or anything like that, it's essentially the science of understanding what the hell is going on with that pie. It's a study of human behavior, not a guide for how we should live or spend our money. Capitalism doesn't mean banks or bosses, socialists just like to associate them and paint a demonic picture of a science for lord knows what reason.
What's wrong with a disparity anyways? When the rich get richer the poor do as well- the best way to make money is by finding a way to get everything to the customer for cheaper, after all. Carnegie may have treated his workers harsher than is legal today, but he sure as

did more for developing this country than any charity has. So basically if you have an agenda against the disparity you're simply upset that someone has more than others. Not that the others are being harmed by the person being rich- on the contrary, they benefit from it- just this person having more irks them. So the poor be damned, we must bring down the rich simply because they're rich, those bastards.
