Recently, I have talked to a doctor and a lawyer (I look forward to the unscheduled but surely inevitable chat with the Indian chief). Both have made politics simple: for them, they typically vote Republican because they dislike paying so much in taxes. What could be more obvious or simple?
These people work hard and aren't eager to give their money away. But that is just half the equation. Doctors and lawyers make more than the average person in probably every country. Relatively speaking, they will always be "rich." But the amount of money they make is always proportional to the average income in their community. Poor people can afford to pay them less than wealthy people.
Because of this, doctors and lawyers - even corporate chiefs - have an interest in the well being of others. For this reason alone, they ought to concern themselves with policies beyond simple measures like tax rates.
First of all, lowering taxes while increasing spending is a ruse. It is like paying less on your credit card while spending just as much each month. The ultimate cost is higher than "pay as you go" options.
Secondly, it is possible to spend money in ways that increase GDP. Not all money is a simple transfer of income. (And while I don't think that subsidizing the poor needs an argument to support it, I'll not even bother to make that argument right now.) Government spending can make an economy more robust: public education, transportation systems, R&D, and regulations are just some of the more obvious ways that a community can create value for everyone. It is worth remembering that Sweden's total tax rate is 50.5% and Mexico's is only 18%. Low taxes do not automatically translate into high incomes any more than high taxes automatically translate into low quality of life.
Most religions preach some variation on the notion that "the other" is an illusion imposed by our limited consciousness. "As you do to the least, so you do it unto me," suggests that the distinction between least to greatest is illusion. Given how communities share so much - from crime rates to average incomes and culture - it may well be that the illusion of "the other" applies in every area - even economic policy.
As it turns out, even the best doctors and lawyers find it difficult to live well when their patients and clients are unable to pay their bills. It might just be that the them is us.
