Is Entrepreneurship the Best Road to Wealth?

Scott Burns recently wrote a column on wealth. In it, he reports on a survey on wealth in America that has some very interesting findings. The young in this country are getting less wealthy, and the old are getting wealthier. As we would expect, our wealth peaks in our 60s as many of us begin our retirement. But, the most intriguing finding to me is related to business ownership:

Citing data from other sources, Mr. Murphy observed that 50 percent of all households with a net worth of $1 million to $10 million were business owners. But 76 percent of those with $10 million to $50 million owned a business, and 89 percent of those worth more than $50 million owned a business.

Burns includes a summary table of the wealth scorecard from this report in his article.
