There is no &quot;now what&quot;.  That&#x27;s the problem.  There&#x27;s only so much &quot;good debt&quot; to buy and it&#x27;s all bought.  These systems depend on continuous growth to function, and unless you can figure out how to sell mortgages to Martians, you are fresh out of growth.  Maybe I&#x27;m wrong, and maybe they&#x27;ll figure out how to have another bull run, but I think they&#x27;ve hit the wall.
