Well, you can’t take it with you. Might as well enjoy your earnings now. Maybe their children or grandchildren don’t deserve any inheritance.
Their point was that they would spend the money either way, so they decided to spend it on something they like more.
My aunt died on a cruise after an accidental dramamine overdose (she was in her early 70s) so I don’t recommend it.
Quite frankly none of us “deserve” an inheritance. That’s the old folks money - they brought up the kids, now the kids are working, so the kids should look for themselves.
Now I would love to inherit, but let’s be fair.
