Now they're stumbling.
Indians are buying fewer cars for the first time in a decade. Chinese are struggling as economic growth slows to a two-decade low.
Even big-spending Brazilians, who like to buy everything from shoes to dental work on credit, are turning thrifty and angry. Hundreds of thousands took to the streets in June to protest rising prices and shoddy public services.
The timing is unfortunate. The economies of the United States, Europe and Japan have gained some momentum in recent months.
The reasons for the slowdown in the BRICs, as the four biggest developing countries are known, are myriad, from a pullback in bank lending in China to crumbling infrastructure and rampant corruption in India.
One constant: The cost of living is rising fast, sapping spending power and the spirits of even those who've done well since the crisis.
Wang Yonghui, a hotel worker in Shijiazhuang, China, bought an apartment in 2006 that has almost doubled in value. But the price of nearly everything else has risen, too, outstripping his and his wife's monthly income of 8,000 yuan (USD 1,300).
In Russia, Daria Ivashkevich, 42 and a mother of two, paid off a loan for her Moscow apartment a few years ago, and no longer borrows to buy smartphones, computers and other items. Still, she's had to cut back on food and travel to make ends meet. "Our income hasn't gone down but because of inflation we have less money to spend," she says.
Consumer prices in Russia have risen an average 9 percent a year since the financial crisis, according to Haver Analytics, a data provider.
But the developing countries snapped back, thanks to a mix of massive government stimulus programs, a flood of bank loans to businesses and consumers and a rebound in prices for commodities, a big source of exports for some of the countries.
