It should provide jobs, schooling and health care. It should accommodate homeless people. The housing doesn't have to be lavish, but it shouldn't be a ghetto either. The next problem is where to build such accommodations. These people argue housing the homeless will bring down property value and that drugs will be brought into the neighborhoods, due to the belief that most homeless people are addicts.
Drugs are present in every community, from the richest to the poorest.
So that argument is really no good. The argument of property value was used against allowing minorities move into neighborhoods in the past. Most people now agree this was a narrow-minded way of looking at things. In fact, it is the paranoia and the quick decision by many people in those neighborhoods that causes the property value to drop. By doing this, we would turn wasted space into something positive.
