> Do we have double the population we did in 2016? Double the resources? Double the technology? If not then why is the stock market twice as high? One easy answer is that the "value" of a dollar is half what it recently was. And that seems to hold fairly true whether you want to use that dollar to buy groceries, a house, a hotel room or a share of a company. If I measure my investments not in dollars but in say, days of vacation (so hotel, food, gas/airfare, tickets to things, etc) then my S&P500 investment is about where it was in 2016.
