This is a sad picture. Unfortunately, I see this almost every day. It is definitely a bad thing. First of all, the state should pay attention and help those people who can not take care of themselves. There is a certain category of people who are used to this way of life. I saw one guy doing a social experiment. He took to his home (from the street) two homeless people - a man and a woman. He promised them to help them return to normal life and find a job. One condition was put forward: they should stop using alcohol. The first weeks were good. He brought them to a normal state, even took them to the theater. But as soon as he did not pay attention to them - they started drinking alcohol. That is, they are so accustomed to such a way of life that they slowly began to reassert themselves to it.
I am sure that these problems are caused by 2 factors:

1. Social assistance of the state (rehabilitation programs, psychological assistance, etc.).
2. This is a person's thinking. If a person is depressed, he begins to drink alcohol. Over time, alcohol weakens the will and desire for a better life. Man as a drug addict, he feels depressed and can do nothing. That is, everything depends on thinking. Different people perceive different situations in different ways. One sees the opportunity, and the other sees grief.
   In any case, in a civilized society to see people who are looking for food in the trash - is unacceptable.
   Thank you
