The pursuit of BMW and other companies also increased the race to offer tax money, tax breaks and property as incentives to private companies. BMW got the equivalent in today's dollars of about $325 million in incentives. But the plant likely would have been successful even if it hadn't gotten a dime of taxpayer money, said Ashley Landess, president of the South Carolina Policy Council.

Politicians were soon trying to find the next big thing and likely gave incentives to companies that squandered the money. A Pew Center report this year found that 26 states, including South Carolina, didn't have an adequate system for evaluating how well tax incentives were working to bring economic development.

"You had one big success and everyone chases the next one," said Landess, whose group thinks incentives amount to corporate welfare that hurts capitalism and competition. It would rather see lawmakers lower taxes to improve the state's business climate.

Also, BMW didn't bring the kind of economic kick that Campbell and others hoped for in individual wallets. Per capita income in Greenville and Spartanburg counties has barely risen faster than the rate of inflation in the past decade, according to U.S. Census figures. The poverty level in both places has increased, and BMW and its related industries couldn't buffer the state from the Great Recession, as unemployment soared past 11 percent three years ago.

Still, per capita income in Greenville County was $26,547 in 2010, about $3,200 more than the South Carolina average.

BMW also has put an emphasis on being green. The company began a project in 2003 to use methane gas generated from a nearby landfill to power some of its plant. Now the project provides half the energy the plant needs. The automaker also takes an interest in local culture, having given $1 million to the Spartanburg Center for Arts, Science and History.
