ajobbins: Some stats here.
Top 1% hold 16.4 percent of the wealth.
Bottom 50% hold only 5.2% of the wealth
What is this 'wealth' they are measuring here? Assets? Wages?
That is useful proxy for many other indicators but I expect you would get a better view from quality of life indicators. For instance here in Auckland it is very possible asset value (and or wage in many sectors) has increased substantially but quality of life has declined fundamentally (traffic, noise, air pollution, etc) due to a systemic lack of urban and suburban planning. Focus on monetary factors can easily obscure what is important.
