An interesting idea, but unfortunately for her, so far few artists succeeded to get on the lists of candidates of the political parties. And more generally, artists may be engaged with such societal problems, but appear far less interested in party politics. An artist as prime minister will remain a dream for the time being.
Nevertheless, I do agree that interactions between members of parliament or municipal councils, entrepreneurs and so forth, with artists may strengthen the imagination and help in redefining problems and finding solutions.
