This astute observation was more interesting than the entire article we're discussing.
Other things to point out is that the tech and housing bubble were results of Wall Street really only having one "safe bet" to push towards investors/funds for pensions and municipalities. So they tried to extract as much profit from the avenues.
However, pushing money into the market in such a rapid fashion distorts it. Nobody thought home prices would peak, when realisitically, they had to at some point. Same with tech stocks during the dot bomb.
A large enough investment in a market sector can displace organic growth, and runs the risk of destroying wealth.
The housing crisis was somewhat caused by people not thinking of houses as places to live, but devices to make money (see: house-flipping).
The long-term growth problem is somewhat caused by people not thinking of jobs as means to create value, but as methods of making money.
