Rich people should build more fountains though. That's a statement that doesn't even contradict the idea that rich people shouldn't exist. They do, and they should be building fountains until we eliminate them. I would also say it's not even liberal especially, but definitely not neo liberal. Throughout human history, where there are wealthy people they are financing public works and art to show off their wealth. They make gardens and parks and statues and temples to raise their prestige, as well as support something they like. Part of the reason most American cities look like shit is because all space was either administered by the government with the lowest possible budget and any spending that wasn't functionally essential(and quite a lot that was) got treated as a sin, or it was used by businesses. Vanity projects should be theater companies and artworks, not space flights and warehouses full of cars.
