I might agree with this if his mother lived in the United States.
I'm not sure what life is like in the Dominican Republic but as many posters have previously stated, the American dollar goes further there. It might be one of those countries where people make 1.50 for a full day's work. I read his mom is an attorney. I don't know what their story is but his mom, sister and Chantel seem very materialistic.
Nothing wrong with an efficiency in my opinion. My first apartment was an efficiency.
