This should help you understand the typical millionaire (Source: Fidelity Investments):

I am not certain why those demographics are important. This site for me has more
handsome men than others. Money is really not a factor for those who have their own.
No, I am not a millionaire, but I live an ok life.

Wow, Orlando, those stats are VERY interesting.  I'm in marketing--I love this kind of stuff!  By your profile name, I thought you were on the East coast, but you're just south of me.  I'm in South OC.
As 61% are married it makes sense that they would take their partner's advice if they want the benefits of the relationship to continue (i.e., sex).  Reminds me of a Jack In The Box commercial..."NONOOKIE"

I'm amazed sole decision maker is only 58%, I guess the 42% shared are just idiots.

If you've had an effective strategy to get you to where you are, and the person you're in a relationship with is not as successful, why in the world would you take their advice on financial matters (or anything that could affect you financially)? Its a bit like taking stock tips from homeless people.
