"Disposable income per capita" is certainly a number, but it's not actually meaningful in this context for a few reasons:
1. "Disposable income per capita" is irrelevant to normal people, as it does not account for how equally that wealth is actually spread. If the top 1% double their income and the rest halves it, that's still a net increase in "disposable income".
2. "Disposable income" does not at all account for the varying amount of cost required to sustain a given standard of living in different regions, even within a country.
3. "Disposable income" is a purely economic measure. As such, it does not measure a large amount things that impact your quality of life, like time off, stress, job satisfaction, etc. A quick look at those non-economic measures will show those high economic measures don't come for free.
