Where does the wealth come from when asset prices go up? The numbers are irrelevant, because they are based on units that go up and down too. My house was worth (say) 100,00 units 10 years ago. Now it's worth 200,00 units. The house hasn't changed, but the units have declined in value. So you need more of those worse units to pay the same amount. A better way of looking at it is with an inert asset like gold. In the 1930s an ounce of gold was about $35, today that same ounce of gold costs about $1800. The gold itself hasn't varied. (It can't, it's a metallic element.) But the buying-power of the USD has declined tremendously; so much so that one dollar today has the roughly the same buying power that two cents did way back in 1935.
