The gentrification of America.
It has been happening in major cities like San Francisco, Boston, Atlanta, Washington and New York for decades. But the results have been controversial.
On Tuesday night, actor and director Spike Lee went off about the "great influx of white people" when he was asked this question New York City resident, D.K. Smith.
SMITH: You mentioned gentrification with some slightly negative connotation and I wondered if you've ever looked at it from the other side. Which is that if your family was still in that 40 thousand dollar home, it's now worth three and a half, 4 million dollars.
SPIKE: Alright, let me just kill you right now.
SMITH: Ok, go for it.
SPIKE: There was a b****t article in the New York Times today and the good of gentrification. I don't believe that.
But Spike Lee was just getting warmed up.
LEE: And then comes the m***k***g Christopher Columbus Syndrome. You can't discover this! We been here. You just can't come and bogart. There were brothers playing m***k***g African drums in Mount Morris Park for 40 years and now they can't do it anymore because the new inhabitants said the drums are loud.
D.K. Smith is the man who ignited the firestorm and asked Spike Lee that controversial question. He is OutFront.
