I don't mean to be personal but...
The company employing you likely paid tax on the money it got, now it passes it to you as wages and you pay "another" tax. The same for investments. Why shouldn't you pay on inheritance? You haven't paid tax on that property before right?
And with an inheritance, the inheritors haven't done anything to deserve not to be taxed. Workers have worked, investors invested, inheritors are basically lottery winners.
People don't like how inheritance tax feels but its actually one of the most logical, fairest, least economically expensive taxes.
