I'm just stating facts. When people die, houses go onto the market.
That's a fact that goes all the way back in history, not anything unique to the boomer generation. Though I think there's a tendency I see often in the boomer generation: Wanting things to be worse for future generations for some reason.
Does it really bother you that after you die, someone else is going to be living in your house and that will be something that will improve their lives?
