So, then, what's the point?
If your estate is large enough that inheritance taxes are a worry, then perhaps you should do some estate planning. Its easier and faster than counting on the passage of a bill.
Once again you make my argument for me. Estate planning involves a lot of expensive lawyers, accountants and life insurance. It can only follow that you must have a hand in one of those cookie jars.
As Zell Miller once said: "How can Americans do estate planning when they don't even know what the inheritance tax will be in five years?"
