So we should willingly accept drastically more dangerous living conditions than other major cities? If we know that safe places like that exist then why don't we try to emulate it? I live in one of those cities mentioned and while it has its own problems like any place does, it's quite remarkable how safe it is. You'd have no problem walking alone down some shady alleys as long as you mind your own business.
