I'm in agreement with those who don't think the spells should be more powerful and such. Basically I think multiclassing should be for specific archtype purposes. A fighter with counterspell, a rogue/thug with a greatsword, a cleric who dabbles as a warlock.
Most of the issue would be fixed with the frontloading of the classes not passing in multiclassing but that doesn't mean the "powers" of a class should be bumped up from lvl 1 regardless of character level. Maybe you should have waited till you were such a good fighter before trying to be a wizard. Or maybe you have a plan.
Also, maybe limit the amount someone can multiclass. Something like 2 until level 8 or 10 then you can dabble in a 3rd.
Regardless of any of this, someone will always find a way to exploit any system so the DM should have a certain level of control on the game (Even if his/her choice of control is none).
And as far as the real life justification of level dipping. I think that comes down to RP. For instance, I like the idea of a fighter with counterspell so maybe I pick up a book on magic at a town and study or peak over the wizard's shoulder when he's reading up at night.
