AFAIK he gives quite a bit of support to charities and causes.
And seems to be a bit more complicated than simply making loads of dosh. Although he has made shedloads. Odd person, probably, but unless you consider him a vandal, and he can vandalise my house any day of the week, seems pretty harmless, and decent.
"Take the water tank on the edge of the Pacific Ocean, overlooking the Pacific Coast Highway outside of LA. Thinking the old tank was abandoned, Banksy painted a caption on the side of it "This Looks A Bit Like An Elephant", and instantly turned it into a tourist attraction and a potential money-maker for two owners of a media design firm that bought the tank from the city of LA with plans to remove and sell it. There was just one complication - the homeless man, Tachowa Covington, who had been living inside of it for seven years and suddenly had his home destroyed.
Banksy heard about the situation, and within hours had reached out to Covington, giving him enough money to get an apartment and support himself for an entire year. This was not enough for the artist. He went on to remove the water tank from his website, and refused to authenticate it for the new owners. The result? Instead of a profitable sale at auction, the tank ended up in a scrap metal yard."
