On the road here in Los Angeles, giving a little rap Saturday at a conference of about 500 people on what else? Wal-Mart. The enormous wealth of the Walton family, and good ‘ole Alice Walton’s purchase of a $35 million painting, versus the poverty of the company’s workers truly blows people away.

And, lo and behold, David Cay Johnston, reporter for the New York Times and author of the “Perfectly Legal: The Covert Campaign to Rig Our Tax System to Benefit the Super Rich — and Cheat Everybody Else,” has a revealing piece today looking at the Waltons and their “hyper rich” friends. Here are a few excerpts:

“The people at the top of America’s money pyramid have so prospered in recent years that they have pulled far ahead of the rest of the population, an analysis of tax records and other government data by The New York Times shows. They have even left behind people making hundreds of thousands of dollars a year.

Call them the hyper-rich.

They are not just a few Croesus-like rarities. Draw a line under the top 0.1 percent of income earners – the top one-thousandth. Above that line are about 145,000 taxpayers, each with at least $1.6 million in income and often much more.

The average income for the top 0.1 percent was $3 million in 2002, the latest year for which averages are available. That number is two and a half times the $1.2 million, adjusted for inflation, that group reported in 1980. No other income group rose nearly as fast.

The share of the nation’s income earned by those in this uppermost category has more than doubled since 1980, to 7.4 percent in 2002. The share of income earned by the rest of the top 10 percent rose far less, and the share earned by the bottom 90 percent fell.

Next, examine the net worth of American households. The group with homes, investments and other assets worth more than $10 million comprised 338,400 households in 2001, the last year for which data are available. The number has grown more than 400 percent since 1980, after adjusting for inflation, while the total number of households has grown only 27 percent.

The Bush administration tax cuts stand to widen the gap between the hyper-rich and the rest of America. The merely rich, making hundreds of thousands of dollars a year, will shoulder a disproportionate share of the tax burden.

President Bush said during the third election debate last October that most of the tax cuts went to low- and middle-income Americans. In fact, most – 53 percent – will go to people with incomes in the top 10 percent over the first 15 years of the cuts, which began in 2001 and would have to be reauthorized in 2010. And more than 15 percent will go just to the top 0.1 percent, those 145,000 taxpayers.”

Let the robbery continue.
