I've been thinking about this a bit recently. You can have a highly successful doctor who doesn't know a thing about managing money. Or you could have a high flying corporate business guy who earns a lot, but spends more than he earns. So to me, it seems that financial IQ is something independent of one's main skill for which they use to earn income.
On the lowest level, I suppose you'd have people who are in debt, and not only do they not know how to get out of it, but they get deeper in debt. On the other extreme, you could have a person who ensures every dollar they have is working to earn a ROI.
So I have two questions:
1) where would you rate someone who only knows how to save money but not know how to do anything else with it? That is, they think "yes, I'm earning x percent on my savings!" without considering rates of inflation and taxes, or at least the option of term deposits
2) what do you think is the financial IQ of the average person?
