You are aware that the person who bought the property 30/40 years isn't the one paying the inheritance tax! When you inherit exactly what have you done to earn that income?
The tax is levied on the estate before the remainder is distributed so its arguable on whom the tax is levied. If someone has worked hard and invested prudently, both for their benefit and for the benefit of their descendants, it is not fair that the government steals a portion of the estate.
