Won't somebody think of those spoiled brats who have had mommy and daddy pay their way through life? Now they're getting less of an inheritance! The horror!
Again, the people most affected aren't the rich, but instead working-class Americans. Pretty much every new tax is advertised as trying screw the rich but instead it hits the everybody else a lot harder because they haven't as much money to throw around in the first place. However, the myth of going after the rich is popular because it taps into innate envy and jealousy. "How dare they have that money! They couldn't possibly have done anything to earn it!"
Most working-class Americans don't have a 5.5 million dollar estate.
And no, the children receiving the inheritance didn't do anything to get the money. They just had the good fortune of spawning from the genitalia of a wealthy person. ---
