John C. BogleWe live in a very risky world and investors should not get "carried away" with excessive allocations to equities, or for that matter, real estate. As always asset allocation and low cost and broad diversification will be essential in earning one's fair share of whatever returns our financial markets are generous enough to bestow upon us.
John C. BogleWhile I haven't read economist Robin Hahnel's work, replacing capitalism would be at the very bottom of my list of priorities - to be considered only after everything else had been tried.

It sets a high hurdle that few investors can leap.
