The 2 grand is only awarded to recent winners of the medal, his award was most likely the 50 bucks a month they received for WWII winners. As for the rest of your post, I don't know, but he sure as he** didn't get rich by winning the medal, he merely saved other American soldiers lives.
The Veterans Benefits Act of 2002 (Public Law 107-330) set up a formula for future increases in the Medal of Honor stipend based on the annual rate of inflation. The new law also provides for a retroactive payment of stipends to cover the period between the act of valor and the awarding of the Medal of Honor. For those previously non-covered months or years, the payment will be based on the rate in effect at the time of the act of valor.
Previously, each increase in the Medal of Honor stipend required a specific act of Congress. The rate went from $10 in 1916 to $100 in 1961, $200 in 1979, $400 in 1993, and $600 in 1998. Under the new rates, the payments rose from $600 monthly to $1,000 monthly. The new rate was reflected in regular monthly payments starting November 1, 2003. On December 1, 2005 the rate increased to $1,069 per month, on December 1, 2006 the rate became $1,104 per month, and on December 1, 2007 the rate became $1,129 per month..
Effective December 1, 2008 the rate is $1,194 per month.
