Piketty Principle
Piketty in his book (capital in 21st centuary) explained the reasons for the widening difference
in growth of economic disparity. He observed that “The rate of return on the investments the wealthy make will normally be
greater than the rate of growth in a nation’s economy and total wealth.”.
This lead to increase in divergence of the earnings of the
rich with respect to poor. He indicates increasing r-g gap(r – rate of asset
return, g – real income growth) . The increasing r-g gap will lead to unrest
and other social issues. The divergence is increasing with time. The skill development, knowledge diffusion can
lead to convergences – ie reduction in in-equality.
