Quick Sad Fact
Long term investing in America doesn't work.
FACT - at the DJIA peak in 1929 the value of the entire index was worth a little over 18 oz of gold.
FACT - today, the DJIA is worth a little over 9 oz of gold.
If 80 years isn't LONG TERM investing, I don't know what is. Buy gold - you won't get rich, because gold is a store of wealth, but you'll do better than buying into the DJIA.
