The most costly form of theft — by far — is not burglary or robbery but wage theft. That is a crime overwhelmingly committed by rich professionals and rarely enforced. So if we really want to get serious about stopping theft, we should allocate much more resources to investigating businesses than putting beat cops on the street.

There’s not actually a well known link between poverty and crime in the way you imply. We’ve just decided that we only care about some people committing some crime some of the time.
