Quote from Martinghoul:
Sounds like an urban legend to me... Broadly, though, it sums up the incentive issues inherent in socialism, if it were offered to humankind today.
However, I would also suggest that the credit crunch demonstrated how capitalism itself has some very fundamental incentive flaws.
So, in summary, currently socialism = long-run economic underperformance and general malaise, while capitalism = extreme boom and bust. On balance, I would probably still go for the latter...
There wouldn't even be "boom and bust"... IF THE GOVERNMENT DIDN'T SCREW WITH THE MONEY!!
