Seems like that should be a problem already. I have family that was in the music industry and collected royalties. They won a few Grammys, so the royalties were substantial. Their estate should not continue to receive royalties indefinitely. Hell, as much as I loved them, they shouldn’t be collecting indefinitely. They worked hard their entire life and because of that hard work, they deserved to live comfortably in retirement until they passed, but they weren’t owed anything they didn’t deserve. And as much as I love their kids, they’re family too, it isn’t as though they deserved any income for something their parent did decades earlier, before they had families of their own.
