"I took the money and ran". This is the freemarketeers concept of creating wealth.
Yup, thats how it works, I take some of the profit I made on Real estate, and some gets invested elsewhere some gets used to make purchases that would not have been made other wise to grow the economy {economics 101}hope it's not too confusing for some on this thread.
You ignore the fact that someone has a brand new house for which he feels he paid a fair price. That sounds like wealth has been created, to me.
