The largest retail store in the US is also the largest globally. Walmart has more than 5,263 stores and $387.66 billion in revenue in the US alone. Sam Walton opened his first store in 1962 in Rogers, Arkansas. Now, US retail employment statistics tell us that Walmart provides jobs for around 1.5 million people, with an average hourly wage of $14.76. That amounts to between $25,000 and $30,000 annually for a full-time employee.
