For crying out loud, Tim. She isn't glorifying being a bartender, she is responding to her critics suggesting it is a lesser job, or something that she should have to apologize for. This is not analogous to Joe the Plumber, who was trotted out there to show that, contrary to the stereotype, there actually are average working people in the GOP (that isn't a case one has to make with Democrats).
Here is the quote with a little more context.
AOC: "I'm proud to be a bartender. Ain't nothing wrong with that. There's nothing wrong with working retail, folding clothes for other people to buy. There is nothing wrong with preparing the food that your neighbors will eat."
