In many countries the standard of living enjoyed by their people has been increased rapidly in recent years. Sadly, not everyone in these countries is so fortunate and many people in rich countries are homeless.
The reasons for homelessness are various, but poverty is undoubtedly one of the main causes. The homeless people may have become jobless and then been unable to pay their rent and so no longer have a roof over their heads. Often, the fact that unemployed people get help from the government prevents this from happening, but not always.
Some homeless people are mentally ill and have no one to look after them. Some are young people who, for one reason or another, have left home and have nowhere to live. Many of them have had a serious disagreement with their parents and have left home, choosing to go to a city and live on the streets. Sometimes they have taken such action because they have been unable to get on with a step-parent.
