Change the Way We Measure Progress:
GDP is a good measure of economic activity — of money changing hands — but a poor measure of progress or well-being. It lumps desirable expenditures (e.g. spending on food entertainment or investment in education) with undesirable expenditures (e.g. the costs of war crime pollution and family breakdown).
A new system of indicators should be created that separates ends (i.e. goals) from means (i.e. the way to achieve these goals). The key goal to strive towards in a steady state economy would be sustainable and equitable human well-being instead of GDP growth (which is only one means towards this end).
The set of indicators should include three groups: the environment the economic system and human well-being.
