First off the guy needs to lock his door. I believe that good quality locks, doors, and an alarm system are a good first step. These items will not absolutely keep someone out, but they do two things. First, they may cause the potential intruder to simply look for an easier target the guy apparently checked twenty homes before settling on the one with an unlocked door. Secondly, they give you a little bit of warning that something is up.
A major source of objection to a free economy is precisely that it ... gives people what they want instead of what a particular group thinks they ought to want. Underlying most arguments against the free market is a lack of belief in freedom itself.
