Recently, the GOOD website printed up GOOD Sheet #4, a nice graph of where the money given to gas stations goes. (GOOD defies description, but it's pretty good. Check it out.) Hard-copies of the sheet are available at Starbucks, but interested viewers can find an online copy here.

It's worth checking out: in a clear, easy-to-read manner, GOOD shows how the profit on gas is distributed and outlines the major factors that drive price. What it doesn't cover, however, is the ways that oil-producing companies actually use this money. Unfortunately, this is also the most important aspect of the oil market.

Oil is, perhaps, the most effective tool for wealth consolidation in the history of the world. Whether through technological innovation, conflict, or the luck of the draw, certain areas and people have ended up with large amounts of crude petroleum at their disposal.

The airlines might have found a tax loophole, and you're it. The travel consultancy firm T2 recently published a worrisome blog post that is gaining traction. The airlines' extra fees, it says, aren't just costing consumers more. They're also enabling the airlines to dodge tax to our government.

Until a few months ago, checking a bag was considered a service that came with the base fare that you paid when you bought your plane ticket. That was taxed at a rate of 7.5%. But now many airlines are charging up to $50 for each bag each way, and because it's not part of the base fare, that fee isn't subject to tax. T2 says that cash belongs to the airlines, free and clear.

So a carrier like United, T2 writer Timothy O'Neil-Dunne calculates, would be cheating Uncle Sam out of tax income of $7.5 million for each $100 million it makes on extra fees. Given that United recently surmised that it stood to make $700 million on its extra fees, that's a lot of cash that won't be going to our schools, our roads, our veterans programs, and our elaborate Wall Street bailouts. Not only do consumers get screwed by these extra fees, they get screwed out of the greater good of tax revenue.

Beijing took some heat in the press for sweeping its streets of the homeless before the Olympic circus came to town, but China's government isn't the only one trying to banish the disadvantaged from places where visitors tread.

According to the main Atlanta newspaper, the Journal-Constitution, cops have been trawling the streets this month dressed as tourists, hoping to catch panhandlers in the act of rustling up money. As of last week, 44 beggars have been arrested.

One of the police commanders in town explains that the frequency and intimidating style of local begging has gotten so bad that it's annoying tourists and scaring them away. And because most tourists who feel accosted by beggars don't return to town to testify, the city had to resort to using officers posing as tourists so that there would be someone around to tell it to the judge. The decoys are even rigged with hidden cameras.

Atlanta, which passed an ordinance three years ago that banned verbal panhandling in a restricted downtown area near the Georgia Aquarium, is far from the only city to place limits on begging. In the Peachtree City, beggars can usually get by silently holding a sign that asks for cash. But ask "aggressively" -- the interpretation, like the one for obscenity, is fluid -- and it's a crime.
