Quote from Cutten:
Double taxation happens all the time. I get taxed on my income. If I spend the rest, I get sales tax or value-added tax to pay. If I invest the rest, I get capital gains tax on that. That's just the way tax works - any time you make a gain, you get taxed, that's the general principle.
If I inherit some money, clearly I am making a financial gain. Unlike income, or capital gains, I didn't actually do anything constructive to deserve that gain. I just got lucky enough to have parents or relatives rich enough to have money and nepotistic enough to pass it on to me rather than some pauper in the third world, or deserving charity. If we are going to tax anything, I think totally luck-based unearned gains like inheritance is, at the very least, just as deserving of taxation as income or capital gains - and arguably more deserving of tax. I cannot really see any reason why profiting from the death of a relative, rather than by your own endeavours and productive work, is more deserving of any kind of tax exempt status.
Now ideally most stuff would be taxed so little that it would not matter very much. But if tax is going to be high, let it be levied on unearned nepotism at least as much as on deserving gains from hard work. I don't think that's idiotic.
As for trying to bring in the emotive side of things, surely taxing someone after they die is far more equitable than taxing them while they are alive. The latter makes them a partial slave for decades, the former doesn't affect them until they are gone and can't feel any pain from it.
