Banksy is a legacy artist. Nowadays, there’s nothing he can do that a twitterbot couldn’t do better.
Banksy's shredded painting shows a deep rooted problem within our society. Rich people will spend million of dollars on a simple painting but give nothing back to their community. The painting is now worth triple the price it originally sold for. The rich will buy the painting in any condition because of the wide scale interest. If our society put the same focus and money on helping those who are struggling, many of our nations problems could be fixed.
