We'll go with this definition of irony provided by the Google: "a state of affairs or an event that seems deliberately contrary to what one expects and is often amusing as a result."

Class warriors wanting to decrease inequality by getting the 1% to pay their fair share, not enter into global trade agreements, and keep jobs in America end up increasing inequality globally by focusing only on efforts to prop up the global 1%, the majority of whom live in the U.S. Sounds pretty ironic to me.
