So how much easier would life be
If 19 million mothafuckas grew to be just like me

from Eminem – Who Knew Lyrics on Rap Genius

Meaning

Society can barely handle just one majorly famous guy with Eminem’s attitude… imagine if there were millions more of him.

The question here implies that the answer is that Eminem would rather his fans to be like him. An apathetic attitude makes a lot of things easier, after all.

Will the real Slim Shady please stand up?

Also a reference to “Role Model” off SSLP. “Don’t you wanna grow up to be just like me?”
