Rather teleological argument from Ms Rand. If the heir manages to keep the inheritance, then they deserved it, however if they lose it, they weren't worthy. Perhaps a new "Ayn Rand" inheritance tax is in order; those heirs who fail to double their inheritance within, say, 5 years, must donate them to needy, friendless orphans, these then have their chance for five years. Imagine all the stimulating entrepreneurship! Now excuse me while I go patent some alloys.
