Piketty is a good example of simple models telling great truths.  He simply looked at something so obvious, its amazing no one else had: that the rate of return on investment must be less than the rate of overall economic growth to lower inequality.  If the opposite occurs, as it has for quite a while, then wealth grows among the investor class faster than the economy in general.  Allowed to run to its natural extreme, all the wealth of the nation (or the world, for that matter) will concentrate in the hands of the investor class.  This does not require more precision than the basic existence of r > g.  The rest is all about how quickly the change occurs, not whether it does.
