I'm willing to bet most burglars aren't motivated to do crime due to suffering from starvation-level poverty; there is hardly ever a "need" to do crime -- i.e., a scenario wherein doing something criminal is the only way to survive. You totally neglect the moral angle and reduce it to a barebones cost/benefit sort of judgement, which is reflective of this popular view of criminals as hapless victims of fate or of society, and who are almost righteous in their choice to do crime. Oh, and the only solution is more welfare.
