As Ed Gentry said - the proficiency bonus is compensated by the lack of armor bonus to AC.
If you look in the DMG, you will notice this reflected in most monster creation guidelines, too. AC is usually higher then the other defenses. (Exceptions are Brutes, I think, which have all the same base defenses, with fortitude in practice being the highest). Likewise, all monster attacks vs AC are higher then attacks vs other defenses.
This is the only justification I could come up with for the lack of Proficiency bonus on implements. I'm playing/running an online game, and one of our players (a long-standing power Wizard/Sorc player) is really let down by this little quirk in 4e.
It also doesn't quite explain away some of the overwhelming powers that other classes get (I'm thinking Piercing Strike - Rogue At-Will DEX vs REF attack) that seem really powerful in terms of TO HIT bonuses compared to most implement attacks.
