Although he is known for multi $billion returns on investments in Coca-Cola, The Washington Post, Gillette and other concerns, Berkshire is an Omaha holding company that owns major insurersIMHO Buffett's entertaining Jim Thorpe all American investor persona serves merely as a "front" to obfuscate the true source of his wealth - selling insurance. It's my admittedly limited understanding of insurance that all roads eventually lead to "names" placing bets with Lloyds of London.
i have referred to Buffet over the years as the Whoreacle of Omaha.
