In November 2012, a prominent American politician criticized corporate influence in politics. He told POLITICO:

“We’ve got to make sure that we are not the party of big business, big banks, big Wall Street bailouts, big corporate loopholes, big anything.”

If you didn’t know any better you might have thought that was Bernie Sanders preparing for a future presidential run. But, in fact, it was Bobby Jindal, the conservative governor of Louisiana, criticizing his party’s defeat in the 2012 presidential election.

The businesses world Jindal described is a narrative that pervades American politics. It’s a modern David and Goliath story — the independent entrepreneur using ingenuity to get a seat at the table alongside greedy, mammoth corporations. Movements like “Buy Local” make buying from small businesses sound like the moral choice for consumers.

Economist Robert D. Atkinson disagrees. In their new book “ Big Is Beautiful: Debunking the Myth of Small Business,” Atkinson and co-author Michael Lind argue that the big vs. small mentality is the wrong way to look at the economy.

The American love for small businesses goes all the way back to Thomas Jefferson. Jefferson’s ideal American was the independent, self-starting “ yeoman farmer.” Big businesses got a bad rap in the late 1800s, when industrial monopolies and laissez-faire economics drove wealth inequality across the country. Presidents Teddy Roosevelt and Howard Taft’s trust-busting ways became American legend. The 20th century brought regulatory reforms that reigned in big business, guaranteeing things like market competition, fair wages, equal opportunity hiring, and environmental consciousness.

Fast-forward 50 years, and the narrative hasn’t changed.

“It’s this sort of drumbeat that we have — article after article, pundit after pundit, saying big corporations are bad,” says Atkinson, adding that he thinks this is a myth. “On average, big companies significantly outperform small businesses when it comes to improving quality of life [for their employees]. They spend more money on environmental protection. They export more. They’re more innovative. They injure their workers less. They hire more women and minorities and veterans.”

Atkinson says it’s not that small businesses are bad, as competition is vital in a free market and the rise of the start-up has propelled technological innovation. But the way politicians and the public compare small businesses to large ones is flawed, he says, and that has serious consequences.

It turns out, big corporations aren’t the only ones with political clout, Atkinson says. Small business lobbying groups are influential because every member of Congress has constituents who are small business owners. The small business sector even has its own federal agency: the Small Business Administration.

As a result, Atkinson says, small businesses are exempt from a lot of the regulations that keep big businesses responsible. Some are cleared from anti-discrimination requirements. Some are able to avoid environmental regulations. They’re given tax incentives.

Atkinson argues that strict scrutiny is a big reason that large businesses do so much better than small businesses. Big companies are under more surveillance from the government and the public. “If you’re a big firm, by and large, you have a reputation to uphold ... consumer boycotts are very real. Shareholder pressures are very real,” Atkinson explains.

Atkinson advocates size-neutrality when evaluating businesses. What if regulators lowered the barrier to entry into some industries, but expected small businesses to comply with all standards within a few years? Atkinson says workers, consumers, the environment, and even the economy might be better for it.
