I've never wished for wealth. I hate shopping, luxury is not my idea of pleasure, and I don't enjoy owning a lot of stuff. I've never been able to understand why somebody would get excited about a widescreen TV or a gigantic house or an expensive car. I drive a 2001 Saturn, and I really don't know what a car could have that this one doesn't. I guess the most luxurious thing I own is my Takamine acoustic classical guitar, which I paid a thousand dollars for because I could actually hear the difference.

The only amount of money I'd ever wish for is the amount that would buy me freedom from working for a living. I've spent my adult life earning my monthly keep and supporting my kids with long, hard hours. I've rarely managed to get more than a few months ahead of my bills, and a couple of times I got a few months behind. I did have one extensive flirtation with wealth (this was one of the main subjects of my memoir) during the Internet stock boom in 1999. But a million dollars in stock options didn't buy me any freedom at all. Instead, it shackled me to my job more tightly than I'd ever been shackled before, and the crazy year that followed (before the 2000 stock market crash wiped out my "wealth") was one of the worst years of my life.

So I don't think wealth buys happiness, and nothing I've observed around me has suggested otherwise. But money sure does have a hold on the public imagination, and it sure gets people riled up. The big public debate that's taking place in the United States of America these days about taxes and budget deficits is worth studying from many different angles. As far as the battle in Congress indicates, the Democratic Party wants to cut taxes on lower and middle class Americans but wants the wealthy (those earning above $250,000 a year) to pay more, while the Republican Party wants to extend tax cuts to the wealthy.

It takes some effort to unpack the real agendas behind these stances. Why do the mass of Republican voters care so much about tax cuts for the wealthy, when Republican voters are actually no wealthier than Democratic voters? I've heard it explained that anti-tax conservatives are "voting their dreams" -- they hope to someday become wealthy, and when they finally do they don't want the government taxing their money away. This is the "Joe the Plumber" theory, and I'm sure there's something to it. But it doesn't explain enough.

I think the ideological divisions here are more about identity and trust. If you don't trust your government, and you don't identify with it as representing you, then you will find the idea of enriching it abhorrent. To enrich a government that you don't feel represents you is to give an alien entity greater control of your life. On a personal identity level, on grounds of culture, lifestyle and ideology, many Americans may feel they have more in common with wealthy capitalists than with government bureaucrats. There's the guts of the tax debate: it's less about economics, more about who we each think we are.

Both sides of this debate have been fired up lately. Senator Bernie Sanders of Vermont made a big splash on Friday by delivering a spontaneous, heartfelt mini-filibuster against tax cuts for the wealthy. Like many who watched parts of his long speech, I found his performance thrilling and his words very persuasive. One of his most memorable points involved proposed estate taxes and the Walton family, holders of the Wal-Mart fortune:

Here is the important point I think many people do not know. I have to confess my Republican friends and their pollsters and their language people have done a very good job. This is the so-called death tax. I think all over America people say this is terrible. I have $50,000 in the bank and I want to leave that to my kids and the Government is going to take 55 percent of that, 35 percent of that. What an outrage.

Let us be very clear: This tax applies only -- only -- to the top three-tenths of 1 percent of American families; 99.7 percent of American families will not pay one nickel in an estate tax. This is not a tax on the rich, this is a tax on the very, very, very rich.

If my Republican friends had been successful in doing what they want to do, which is eliminate this estate tax completely, it would have cost our Treasury -- raised the national debt by $1 trillion over a 10-year period. Families such as the Walton family, of Wal-Mart fame, would have received, just this one family, about a $30 billion tax break.

I find it hard to believe when we are talking about massive cuts in programs for working families, when we have this huge national debt, that anybody would be agreeing to lowering the estate tax rate to 35 percent. That is what this agreement does and I think that is a very bad idea.

Bernie Sanders showed much bravery in speaking these words, because it seems almost shocking to single out an American family by name and question their right to keep their own fairly-earned wealth. Anti-tax conservatives often charge that pro-tax liberals are trying to use taxation to engage in "class warfare", and singling out an American family by name might feel like a step in that direction.

But it is also shocking to realize that a single family can hold onto $89 billion dollars in wealth, and we must wonder why it shouldn't be their responsibility to contribute more of this wealth towards paying off the government debt. Is this class warfare? I don't hate the Walton family, and I certainly wouldn't want to punish them. But there's a very good reason why Democratic/liberal economists are calling for holders of extreme wealth in the USA to pay much more taxes: the government is badly in debt, and these individuals are the ones with the money. Seems like a pretty clear case to me.

But, as I mentioned above, debates over taxation are fraught with notions of identity and trust. What are we really talking about when we talk about taxation? Are we on the playing field of economics, or of culture and symbolism, of repression and resentment and control?

The fact that economic forecasters don't predict anything close to a balanced budget under either the Democratic or Republican taxation proposals makes the situation even murkier. The fact that President Barack Obama, widely suspected of being a closet socialist, is actually a closet Taoist wishing to find a perfect balance between both sides of the debate makes it murkier as well.

Meanwhile, I wonder how the members of the Walton family must have reacted when they learned that they'd been singled out by name in Senator Bernie Sanders much-publicized speech. It's strange to consider that this family exists among us. Do they actually live like Richie Rich? Do they regularly give large segments of their wealth away to carefully chosen charities?

I hope so. I can't imagine what else they would want to do with all that money, or how else it could be doing them any good.
