A woman behind the counter at the McDonald’s in southwest Ohio showed Rep. Tim Ryan the math she was trying to work out last week: filling up her tank would be $20 cheaper in West Virginia, but would that cost less than the gas she’d use on the drive there and back? And what about her shifts, or taking care of her three kids?

Meanwhile, the companies that own whichever station she ends up at are all reporting billions of dollars in profit per quarter.

“They’re making huge amounts of money,” the Ohio congressman and Senate candidate told CNN, “while putting the squeeze on the worker.”
