In most of the world today people tend to be segregated, mostly along economic lines. This division can block us from meeting and talking with people as equals and can be a barrier to social harmony.
Residential segregation takes place where the well-off buy themselves out of poorer neighbourhoods and rarely visit these places. The poorest often do not even feature in the mental maps which many of the rich hold of their home city. People in the poor parts of a city rarely spend time in wealthier areas and vice-versa.
