That is such nonsense. Adjusted for inflation the dow is up a lot.
This is true.
Since 1970 the DOW is up about 1200% after considering inflation. Assuming of course that inflation is determined by a basket of purchased goods. (either CPI or GDP deflator)
If you consider real inflation to be the value of the $US as it relates to the value of gold, then the DOW hasn't returned or lost anything during that time period.
If you consider real inflation to be related to the M3 money supply, then the DOW has returned about 850% since 1982.
My personal opinion is that using the value of the dollar relative to gold is the poorest way to measure inflation as the change in price of gold has very little correlation to the change in price of frequently purchased goods.
The use of M3 is logical but I don't think it accounts well for actual buying power. I do, however, think that M3 is valuable in measuring inflation as it relates to broad based index nominal values.
GDP deflator (or CPI) are probably the best thing we've got for measuring actual purchasing power changes.
