Why would you avoid touching prinicpal?
So, if you have $1 million in this example, live off the earnings, then when you pass away, what of the $1 million principle remaining? Do you want to leave money to heirs, to charity perhaps? Do you want to make sure money is left over for a younger wife who is likely to outlive you?
I think it depends on if you want to have substantial funds remaining after you have passed away.
Yes, I wouldn't want to be hoping I die before I go broke.
I don’t have a younger wife, and I’m not turning gay any time soon. But I do have 4 kids, so it’s ok if I didn’t spend all I had.
