You might think about it a little deeper. Capitalism, self-interest and profit seeking have pulled more people out of poverty in the last 100 years than the entire remainder of human history before capitalism took hold.
Giving it all away is often the worst thing that can happen to the money, and to the recipients. Look up what happens to local farmers in Africa as a result of the USA's "generous" food aid. Giving it away is much harder to do right than just doing what each person does best. Bill Gates did much more good for the world as CEO than he has blowing it all on mostly wasted investments that often hurt the world. He has gotten better recently, though, and that's to be expected. Practice makes perfect.
Of all the ideologies, I also feel capitalism and profit seeking have been effective. But there are limits. Capitalism and profit seeking is also responsible for the destruction of our environment, the shameful industry called slavery, and the obliteration of entire peoples and cultures in the interest of money.
I believe that there should be righteous
purpose behind capitalism. A man like Steve Jobs was riiich, but his work was not solely making money; he improved people's lives with his work. The money enabled him to
continue to do it. To put his "dent in the universe."
I don't advocate handouts, as I mentioned. I am for using money to improve people's lives. Don't hand out money, finance training and education, build infrastructure, provide food (at least temporarily) to the desperate, advance technology (such as renewable energy), etc. While
some philanthropy is misguided in
it's execution, the idea to use personal wealth to attempt to improve other people's lives is above reproach. Just do
something other than make money, or at least have people do something meaningful with it
for you.
In other words, making money just to have more is pointless. At some point, you should be able to say "this is enough, let's see what I can do with the rest of it to make this world better." Kindness is never, ever wrong. And the wealthy have the
opportunity to be the kindest of all, since they can afford to be.
