With a savings rate of 8% (roughly that of the American economy) and GDP growth of 2%, wealth should rise to 400% of annual output, for example, while a drop in long-run growth to 1% would push up expected wealth to 800% of GDP. Whether this is a “law” or not, the important point is that a lower growth rate is conducive to higher concentrations of wealth.
