Why you would want to be in the body of somebody that is supposedly discriminated?
(SPOILERS)
According to Jordan Peele himself, Blacks are discriminated for being black.
In the movie you have some white guy that want to use the body of a black guy, which means... he would be treated like a black guy. If Jordan Peele really thinks that blacks are so discriminated, why anybody would want to use a black body? Does that make any sense?
Perhaps the truth slipped through Peele's subconscious. He knows that a meh director like him can be praised as the new Hitchcock just because he's black. Nowadays, having a black body is gonna give you access to advantages, quotas and victim cards, Peele himself knows that better than anybody. Not a bad deal if you wanted to use a new body...
