GDP growth has no strict correlation to stock market returns. Why not? Because corporate profits (eg the S&P 500) can grow far faster than GDP, as they did from 2002-2014.

You should not expect stock market returns to mirror GDP growth. The S&P 500 is not strictly representative of US economic performance, which is precisely why the huge corporations did so well with the cheap dollar and significant global economic expansion while domestic locked companies didn't fair nearly so well.

Your point that the S&P 500 represents large US companies, rather than all US companies, is well taken. Still, the process of centralization you describe (where most gains go to past winners) can't continue indefinitely; the S&P 500 companies (at least the ones in the US) can't account for more than 100% of US production.
