I think that's a rather pessimistic view on things. Greta isn't alone, she's one of the more prominent figures in a global movement demanding change. A movement which is rapidly gaining momentum and effectiveness. She isn't a symbol of 'what might have been', she's a symbol of what's to come. I know that all that's happening around the world is frustrating and scary, but it's important to remain optimistic. Pessimism only benefits the status quo.
