This document is an introduction to a book about class in America. It discusses how class has become an unspoken topic in society, yet the gap between rich and poor continues to widen. The nation is becoming more class-segregated, with the poor isolated in poor communities and the rich living separately behind gates. While many citizens want to believe the US is class-free, this is not the reality. The introduction calls for an open dialogue about class to understand how it intersects with issues like race and gender.
