It wasn't enough that shopping centers were empty. Now hotels and even apartments are empty. Those who are homeless often sleep by freeways, and there seems to be some social service work, but still, for example in Los Angeles, there are thousands of homeless people. What are the barriers? Are there good examples of situations where the homeless are in some type of group/individual housing? What is the invisible catalyst? Because the homeless sometimes do have transfer payments that would make it possible to pay rent, and some could work if they had hope and knew what kind of work they might do.
