"Worn out" is more to the point. Now given my suggestion that the threshold be raised, and I'll accept Ben's figure of $20 million as reasonable, I'd like to see the guy who leaves more money than that who scrimped and ate beans all his life.
The overwhelming majority inherited enough to make a lot more the easy way. The ones that didn't likely (with the exception of a few celebrities and athletes) made their millions by deception, exploitation or outright fraud.
It's just become tiresome reading endless stories of "business geniuses" praised for making zillions of dollars with great new ideas and then reading about their convictions for fraud.
