Crime is a social phenomenon that can not be separated from society itself. As a result, crime will be a problem facing every country ..
So what is the background so that crime continues to occur in the world ??
Economics is the main responsible for increasing crime rates obviously. If someone cannot make his end's meet, He or she start seeking illegal ways to earn sufficient money for their family's needs. If Income levels of society increase, Crime levels will start decreasing as a result of this economic well-being . The more money people have , the less crime they commit.
All poor people doesn't need to be criminals. You are generalizing and insulting them at the same time. Let me give you an example. Moldova is a country in Eastern Europe and it is generally considered to be one of the poorest nations in the world. On the other hand, Gabon is an African nation which is awash in oil-wealth. But still, the crime rate in Moldova is much lower than that in Gabon.
