The fact that this alleged insurance executive is complaining about being taxed at 55-60% tells you, right there, that he's not one of the people who are in the Ayn Rand, Superman Contributors To Society, mold. People who are taxed at 55-60% are working for a living and being taxed on their incomes, which are high, yes, but which are paltry in comparison to the people who REALLY own the major enterprises of the country -- the Gateses, the Dells, etc.
Those people are taxed at 15%, if that, and even when the top income tax rate was 91%, they were still only being taxed at 25%. That's the capital gains rate, and that's what the REAL entrepreneurs in this country pay. Andrew Carnegie didn't get rich by stuffing his salary into a mattress. He built up an enterprise and sold it for hundreds of millions of dollars. He didn't pay ANY tax on that, but do you really think he would have declined to undertake it if he'd had to pay 15%, or even 25% of it to the government?
So no, Noonan's poor insurance executive is NOT one of Rand's exemplars. He's a well-to-do but far from rich working stiff and I don't blame him for feeling that he shouldn't have to bear the burden of higher taxes, but if he decides to quit, there will be a dozen hungry young 'uns ready to take his place and do his job, and nobody will miss him. The idea that he has some sort of special knowledge that the economy cannot do without is simply nonsense.
Finally, the reason taxes on those well-to-do are going to go up is that they have enabled policies which have impoverished enough voters to demand it. Noonan's insurance executive no doubt likes the present system under which people can be denied insurance just when they need it because they failed to mention trivial and unrelated medical problems when they signed up, but it is precisely because such abuses were allowed that health care reform is being demanded, and it's quite possible, isn't it, that this insurance company executive is one of the people who got promoted for aggressively enforcing that policy (it is a fact that insurance companies paid bonuses to people who did this). I don't think insurance company executives are all rats, but as a collective entity they ACT like rats, and force us, at the legislative level, to deal with them as if they were. They had an opportunity to express their beneficence and they chose not to. They have no right to complain now.
