Why did McDonald's move away from being a playful place for young people with like playgrounds where people could jump around and stuff, to being this like soulless depository for food where you have as little interaction with people or the environment as possible?

Along those lines, why did they completely remove the Ronald McDonald and the Grimace and the burglar guy? It's like everything in the entire world has been streamlined to the point that it's like for robots and not for people.
