ON FEBRUARY 12, House Majority Leader Eric Cantor (R-Va.) sent a message to his 62,550 followers on Twitter: "Small business is the job growth engine in this country and we need to pursue policies that reflect that reality to create jobs." Cantor was wrong on both counts. Despite overwhelming conventional wisdom to the contrary, small businesses are not the engine of growth.

The category officially includes the "mom and pop" firms with fewer than 10 employees that most people think of when they hear the term. But companies with hundreds or even thousands of employees (depending on the industry) are also eligible for benefits and other preferences; they win the coveted designation by virtue of the fact that they are small relative to other firms in their industry.
