I'm always fascinated to read studies on income, wealth, savings patterns etc. for different countries and demographic groups. But there are some key variables that always seem to be missing from such studies:

1. Correlation of Net Worth and IQ
- yes I know that there are lots of studies showing that higher education leads to higher income, but the link to higher wealth isn't so strong. There are even indications that education isn't much help in getting rich - lots of self-made millionaires built up a business without a college degree. But, this doesn't mean that these people weren't intelligent. Forrest Gump not withstanding.

2. Correlation of Net Worth and religion.
- you'd think that some religions would be more compatible than others with accumulating wealth. And within a religious grouping you'd expect a correlation with how "strictly" religious someone is and their net worth. After all, you'd expect Christians that don't tithe 10% of their income to end up with greater net worth. But this relationship might be skewed by a small number of high net worth tele-evangelists!

Then again, such studies would not be PC.
