Many hispanics have made their own neighborhoods in small to mid sized cities. I have had this conversation with many many people before and the mindset so many people in NYC have is completely backwards. Most minorities in NYC do not OWN, they LIVE there, but they don't OWN. Once the interests shift, it's all going to the highest bidder and one can't really blame the landowners trying to capitalize.
Even if minorities did own their home's. The city would just catch em with property and home ownership tax. Renting or Owning, Gentrification is going to tap ya pockets
