How billionaires made their money tells you a lot about why billionaires are good for the world economy.
Most billionaires did not inherit their wealth.
A study by research firm Wealth-X explains how they generated their fortunes.
Most billionaires put their money into publicly traded companies found on the Stock Market.
About 36.4% of their portfolios were allocated to this asset class.
Another 35% of their net worth is placed in privately held companies.
That leaves about 26.4% in liquid assets such as cash.
They hold the remaining 2.2% in real estate and luxury assets.
Billionaires can be classified into groups.
