Pumps' Perplexities

It appears that the "home building/housing" market
is now effecting the New York Stock Exchange......The
"housing boom" appears to be over......But why are
people and the stock market surprised?........

Am I wrong in this logic, which follows?.......

Land owners want to sell land.......They want to sell it
to housing developers.......Housing developers want
to sell it to building contractors......Building contractors
want to sell houses to people........People want to
sell their "old" house so they can buy the new one.......

Now who has the money to buy the "old" house.......
Not everybody can afford to buy the "old" house......
SO......Money lenders GAMBLE and lend money at
low rates to people so that they can buy "old" houses.....
If, when the loan rates change, the people can not
afford the "old" house anymore.......The money
lenders start to CRY.......And everybody looks at each
other and asks the question. "What happened?".......

It seems that if the money lenders want to "recoup"
their loses they ask the land owners for money.......

The big financial circle of "money" has broken because
the people who could not afford the "old" house should
not have bought it in the first place.......Pumps
