But the real America has changed. On Monday, the biggest restaurant chain on the planet, McDonald's, lined up on the same side as the Humane Society of the United States on a major issue of animal welfare. It informed its pork suppliers that they will have to stop confining pregnant sows in "gestation crates" that are too small to let the animals turn around.
McDonald's buys 1 percent of the pork sold in this country. When it tells pork producers to jump, they ask, "How high?"
_Most Americans may not rank animal welfare high on the list of their chief concerns. But given the choice of food produced more humanely or less humanely, enough people will choose the latter to make continued indifference a bad business strategy.
McDonald's was preceded by such mainstays of American consumer culture as Burger King, Wendy's, Sonic and Winn-Dixie stores, which have moved against gestation crates. Smithfield Foods -- the world's largest pork producer and one of the most reviled -- has also promised to eliminate these cages by 2017. These are not companies whose customer base consists of vegans in plastic shoes who regard meat as murder.
It's no surprise that Whole Foods Market has built an empire partly by making animal welfare part of its identity. The chain is also known for rarefied offerings and high prices. But retailers like Wal-Mart and Costco, which specialize in mass-market products at bargain prices, are on board as well. Their private label eggs all come from uncaged hens.
In the past seven years, cage-free eggs have increased their share of sales to 8 percent up from 2 percent. A substantial number of Americans are willing to pay a bit more to avoid a conflict between stomach and conscience.
They may not have to. A 2007 study conducted at an Iowa State University research farm found that "group housing may produce pigs at a lower cost than individual gestation stalls in confinement facilities."
The egg industry is likewise adapting to changing norms. The United Egg Producers recently reached agreement with the Humane Society to support federal legislation mandating better conditions for laying hens.
Most of these birds spend their lives with just 67 square inches of space -- smaller than the size of a standard sheet of paper. The bill would increase it to at least 124.
