The dow multiplier supposedly accounts for inflation but what is really different from years ago is that most of the companies in the dow 30 are different now, compared to then. Apples to oranges to compare dow across decades.
But inflation is a bogus number since food and gas are not included in the calculation and those are the things that have doubled and tripled in price.
