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.
But is the FR about how to get rich quick or about the welfare of American Republic? You can get very rich while living in the middle of a ruined country. Is it what would make you satisfied?
