Widening gap between rich and poor

Just last week, there was a newspaper article about poverty becoming prominent. When people think of poverty, it is usually between those of the developed and developing countries. However, not many people really focus on the growing gap of rich and poor neighbourhoods in an urban centre and this is a problem.
As poverty is on the rise, people are becoming more aware of how there isn’t just a gap between countries, but even gaps between people living in the same city. Poverty is a huge problem in that most of the people living in poverty do not have proper jobs, and thus no proper housing. As apartment rents are also on the rise, this forces even more people into poverty and out on the streets.
People living in poverty also tend to stay in the same neighbourhood as each other. These neighbourhoods are associated with poor housing, waste dumps, unclean areas, dangerous areas, and so on. Because of the same type of people living in the area, social services that want to help these people will tend to be in the same area, thus even attracting more people in poverty. Therefore, how can the government help to relieve some of this gap between the rich and the poor so that certain areas can stop being associated as dangerous areas or poverty stricken ones? That is a complicated question to answer because so many areas are associated with poverty already and the gap between the rich and the poor just continues to widen everyday.
