Like for three reasons:
- Adopts a broader definition of 'national wealth' beyond GDP
- Overcomes *ignorant* majority rules issue of democracy
- Data / predictive model driven policy enforcement, none of this finger waving!
Still though, somewhat of a shame that money is still seen as the bottom-line mechanism of motivation, and secondly, I don't necessarily agree that policies should be determined solely by the betting market. Didn't we learn something from the market crash? Even the experts can be guilty of jumping on the bandwagon, not predicting a low probability event and totally missing the target.
