Helping the homeless in a nongovernmental way. The United States has around 553.000 homeless people. Most caused by the gap between increasing housing costs and stagnant incomes. In Venice, many of these are trying to survive by making art. This because it’s the only form of income available. Unfortunately, nobody feels the urge to buy art from a homeless person. Airbnb will host the biggest art museum by tapping into their 7 million places all over the world, making it the biggest art museum ever.
