The difference is that the mainstream left-wing themselves routinely say that they want equality of outcome:

Paul Krugman's -- "we should try to create the society each of us would want if we didn’t know in advance who we’d be."

Or as Ezra Klein put it -- "In truth, equality of opportunity and equality of outcome aren't opposites. They're partners. Companions. Inseparable amigos. You can't have real equality of opportunity without equality of outcome. A rich parent can purchase test prep a poor parent can't. A rich parent can usher their children into social networks a poor parent can't. A rich parent can make donations to Harvard that a poor parent can't."

Or Jonathan Chait -- "the attempt to draw a distinction between equality of outcome and equality of opportunity collapses immediately."

No mainstream right-winger is getting anywhere close to arguing that people should starve to death.
