[Sesame Street] Why is there an enclave of monsters in NYC? What is the history of the monster people?

I've been watching Sesame Street with my kid - and to get over the mind-numbing boredom of watching the same set of episodes over and over again, my brain wanders, and asks:  why are there monsters in NYC?  Where did they come from?  Are they recent arrivals, or is there a long history of monsters in the US?  If so, was there always integration?  Was there monster units in WW2?  Is there a monster bill of rights?  So many questions!

The Muppets were the real first inhabitants of the Americas, before humans crossed the Russia-Alaska land bridge. The period between that crossing and the arrival of Europeans is one of nigh-constant warfare between man and puppet, as both sides fought for dominance. 

With the arrival of Europeans, the game changed. The Muppets jumped into bed with the colonizers; their newfound edge in imported firepower plus their natural resistance to European diseases completely and irrevocably destroyed the balance between the human and puppet natives. Muppets would ride at the vanguard of every expansions, guiding the foreigners straight to the heart of their ancient enemies. 

Of course, this doesn't mean that the Muppets held a unified front. Muppets fought on both sides of the major colonial conflicts; much of the Muppets population of London descends from Loyalist Muppets who fought alongside the British during the Revolutionary War, for instance. But with the Revolution, many Muppets became official American citizens, though they would never fully lose minority status. This led to issues during the urban growrlth of the 50s through 70s, as Muppets often fell victim to "redlining" practices, and neighborhoods with growing Muppet populations suffered issues from "white flight" and related problems. Through this, "Muppet slums" became something of a self-fulfilling prophecy, resulting in area's like Chicago's "Felt Harlem" and New York's "Sesame Street".
