Since I've never had to put that last sentence to the test in any real way, I can't attest to its truth. But reading all the press about Thomas Piketty's Capital in the 21st Century, currently the #1 book on Amazon, has made me think about the song again. One main gist of the book, as far as I can tell (I haven't read it yet), is that since the rate of return (r) on capital greatly outperforms the growth of economies (g), the already staggering gap between rich and poor will continue to grow, unless something is done about it:
Mr Piketty is not arguing that r>g means that rising inequality is inevitable. Indeed, that is close to the precise opposite of his argument, which is that r>g is a force for divergence in the economy which has at times been countered by external forces, and which can and should be similarly countered in [the] future.This means that, as things are now, those who have or inherit money make more money than those who work hard, even if they work much harder than the haves do. I don't know how accurate Piketty's analysis is, but one recent study about wealth disparity in the U.S. concludes the following:
Multivariate analysis indicates that economic elites and organized groups representing business interests have substantial independent impacts on U.S. government policy, while average citizens and mass-based interest groups have little or no independent influence.Little or no independent influence: i.e., common people.
