A problen in any mericratic system is accounting for personal bias. Its very hard for some people to see someone do something different and assume they are as good or better then themselves.
THEY went to college or THEY didn't and all of the personal reasons they assumed when making that decision get reapplied to others.
THEY didn't get where they are by being hired off of well studied hiring mechanism so why would think it needs changed, the old system works for them.
