>>> and sad above all the fact that we have living conditions such that such people generally exist.

Now, let’s talk about living conditions. In all major cities, at least in our half-millionaire, there are centers of social adaptation of persons without a certain place of residence and occupation. Every boy knows about their existence and even sometimes appears there - to wash, sleep a couple of days and drop back on the street. Because in these centers you can’t drink and you need to work at least a little. Therefore, it is easier to dig up to the patrol that passes by than to squeeze to that center.
And in general, yes, sad that there are such people, but the conditions of life here absolutely have nothing to do with it.
