Last week's Supreme Court ruling on the health care law might have made Roscoe Filburn a little happier.

Filburn was an Ohio dairy farmer who had a beef with the federal government, one he took to the U.S. Supreme Court in 1942. He lost.

When Should A Country Abandon Its Own Money?

Enough already with the krona?

Iceland is a tiny nation in a big financial mess. It's still recovering from the aftermath of the 2008 global economic crisis, which caused a domestic banking collapse.

Its currency, the krona, is also in really bad shape. That's led Icelanders to pose an existential currency question: Should they abandon the krona?

One key problem is size. Iceland has about as many people as Staten Island, so there just aren't that many people on the planet who need to use the krona.

"There are more people using Disney dollars," says Arsaell Valfells, an Icelandic economist.

China's Giant Pool Of Dollars

There is an advantage to strengthening the currency for people in China: It makes their imports cheaper. A clerk counts bank notes in a bank in Nantong, east China's Jiangsu Province.

China's central bank is sitting on a giant pool of U.S. dollars. It's the world's biggest holder of foreign reserves, worth over $3 trillion at last count.

All that money has piled up because every year, China exports more than it imports; it runs a trade surplus.

There are lots of reasons for China's trade surplus. In the past few decades, China has built an amazing manufacturing ecosystem. It's become the factory to the world.

The Secret Document That Transformed China

In 1978, the farmers in a small Chinese village called Xiaogang gathered in a mud hut to sign a secret contract. They thought it might get them executed. Instead, it wound up transforming China's economy in ways that are still reverberating today.

The contract was so risky — and such a big deal — because it was created at the height of communism in China. Everyone worked on the village's collective farm; there was no personal property.

"Back then, even one straw belonged to the group," says Yen Jingchang, who was a farmer in Xiaogang in 1978. "No one owned anything."

Why A New York Cheese Buyer Hangs On The Euro's Fate

David Kestenbaum NPR

Among the chilly aisles at Murray's Cheese Shop in Manhattan, the entire continent of Europe is represented. Something like 60 percent of the cheese in Murray's comes from the continent, according to Aaron Foster, a cheese buyer at the store.

For all the talk about how the European debt crisis is effecting the global economy, it can be hard to connect it with daily life here in the U.S. Here's one link: Aaron Foster's bonus depends on how cheaply he can buy cheese from Europe. And the price of that cheese is driven largely by the strength (or weakness) of the euro.

"I don't want the euro to fall apart," says Simon Wolfson.

Lots of people don't want the euro to fall apart. But Wolfson feels compelled to say so because he's offering a $400,000 prize for figuring out how to dismantle the euro.

Wolfson — aka Lord Wolfson of Aspley Guise — is the CEO of a big retailer called NEXT. He has argued against the UK joining the euro, but his company has stores all around the euro zone.
