It is and always will be an "estate tax" or an "inheritance tax," because death has no monetary value in and of itself and thus it cannot be taxed (unless one believes that money is more important than life itself). It is erroneous and a partisan distraction to call it a "death tax" when it is clearly a tax on wealth to be disposed at death.
So, please stop scaring average people into thinking that their deaths are going to be taxed. Death cannot be taxed. Although, I admit that it can be taxing.
