the so-called death tax

No sooner do I write something complimentary about Ron Paul than he says something with which I disagree. He is in favor of repealing the so-called Death Tax (to be fair to Paul, he's in favor or repealing all taxes). The Estate Tax allows up to $2,000,000 tax-free to go to beneficiaries before the rest is taxed (usually at around 20%), so what's the problem?
