Why Can't Thieves Make an HONEST Living?

Since Brian purchased his Escalade, his car has been rifled through twice with some items being stolen and last night was hit #3. This time they stole his rims and wheels, which he recently purchased (twice, but that's a whole other story). They used our neighbor's stone bricks and a jack to keep the car off the ground and left all the lug nuts laying around. I just don't understand why people feel that they have the liberty of taking things that aren't theirs, but then I don't have the mind of a criminal either.
