The economic status of the couple does not seem to make a difference in most relationships. Having a lot of money is not a guarantee that finances will NOT be an issue, nor does living in poverty. However, the discussion and managing of the money will make the difference in the relationships (Goldsmith 2006).
... but what you've BECOME, in getting what you have.
