It was your father's. The question is how much should transfer over to you.

As for "detrimental", I understand you to be arguing that having a rich parent is detrimental because you get hit with this tax. I'm pointing out that having a rich parent and getting hit with this tax still leaves you better off than having a poor parent and not. So on balance you're still better off having a rich parent.

Better off is not "detrimental" in my books.
