It's your poor and middle class who do not have the means to deal with the crime who suffer the crime brought on by opportunistic criminals. Mundane examples are people have had their third and fourth catalytic converters stolen. It may not be a lot of money to you, but for your average worker, it's a day or two of inconvenience and a few hundred each time --money that now has to be reallocated.
The few possesions we had were taken. The most unfortunate was my wife's grandmather's wedding band. It probably wouldn't have fetched more than 20 or 30 bucks, but given that it was a family heirloom from WWII-wrought Finland, the sentimental value was high.
Being white and working for the government in a predominantly minority area, I'm sure I was stereotyped as being able to handle some abuse (in fact my neighboor informed me so). Fortunately we didn't own anything of serious financial value, but having your personal space violated by petty theives is not a pleasant experience.
