Chances are you know someone who works at Walmart.
The discount retail store employs the most people of all publicly traded, American businesses with a staggering 2.3 million workers on its payroll. It's also the second-largest online retailer behind Amazon and employs several times more people than its closest competition.
But, of course, these workers from these top businesses don’t make up a fraction those who work for the U.S.’s top employer: the government. A staggering 22.3 million people work for the U.S. government — but that’s not just politicians or their staffs. It includes public school teachers, police officers, post office workers and those working at your local DMV, among other government agencies.
