How the Rich Got Rich

Where it gets interesting is how the top 400 made their money:

• Wages and salaries:  8.6%
• Interest: 6.6%
• Dividends: 13%
• Partnerships and corporations:  19.9%
• Capital gains: 45.8%

Obvious conclusions:

• Working for a salary won't make you rich.
• Neither will making only safe "income" investments.
• Neither will investing only in large companies.
• Owning a business or businesses, whether in part or partnership, could not only build a solid wealth foundation but could someday...
• Generate a huge financial windfall.
