1. Median disposable income, and standard deviation
   
2. Median free time per week and annual holiday allowances
   
3. A much more vague notion of work fulfillment.

From the plutocratic point of view the useful measures are:

1. Financial productivity and 'added value'
   
2. Time in work (on the assumption that more work means more value created - which is a silly assumption, but a popular one)

The irony is that disposable income and leisure time are two of the biggest drivers of individual spending, and an economy which is strong in both has a good chance of being strong in more traditional ways.
