"What Arnold did do with his winnings up to this point was shrewdly save and invest them so that by the time he arrived in the states in 1968 at age 21, he had about $27,000 to his name."
I doubt he had anywhere close to that. Most bodybuilders today aren't liquid 27,000 in today's money. When he 1st came to America he couldn't even get his own apartment which wouldn't even knock a dent in 27k in 1968
