Warren buffett- the oracle of omahawarren buffett came from a middle-classfamily in nebraska. from a young age, he understood the value of investing money and gaining interest on that investment.  he worked hard at several jobs, but what made him one of the wealthiest men in the world was his gift for allocating capital within a free market system.  in other words, he found companies that he thought would be successful, and invested in them at a reasonable price.  warren buffett is an example of a man whose wealth is owed largely to the free enterprise system. buffett was able to allocate his money however he wanted, investing in businesses that he thought could compete effectively. without the free market system, he would not have the right to invest however he wanted, and would not have become so wealthy.
