I know they unfortunately had to play to the well to do, raise my kids through other's methods, Yuppie set in recent years. I mean, no wonder why SS doesn't have the dark and dusty gritty city street feel anymore. There Neighborhood has been gentrified (that's the word, right?). Look at a normal city street... Starbucks and snotty restauraunts, and yuppies all over the place. Poor people live in (ironically) the suburbs, or smaller places outside of the busy street apartments.
The only difference between real people who live in the city and Sesame Street is that when they clean that street up, the SS residents were able to afford to live there.
