To cause some problematic person, issue, or situation to disappear or become resolved simply by desiring it to happen or ignoring that it is a problem at all. A noun or pronoun can be used between "wish" and "away." Look, I know you want to wish away this problem with accounting, but if we don't deal with it now, we could be looking at criminal charges down the line. This generation just tries to wish away the challenges facing the planet by complaining on social media, without actually taking any meaningful action. I know your little brother can be irritating at time, but you can't just wish him away—he's family, and you need to look out for him!
