Some families have little money, but are willing to lend what little they have among each other. Some families have plenty of money and are willing to lend to each other. Some families have plenty of money, and think that it is poor form to lend to family.

People in my extended family go out of their way to help family members when they are down; for instance covering a few college loan payments or providing a bed to sleep on for a few weeks, but going to them for a business loan? That is not done, even with comparably small amounts of money. I kind of always assumed that was the common attitude, but I guess not.
