In a general context, or in the context of what we're talking about here? In general, I don't know, in context... yes. You can get most kids on board with almost anything, and those you can't, you can generally abuse or otherwise force to submit. They're not set in their ways, they don't have as clear a sense of the world, and their impulse control usually stinks.

There's a reason that everyone, for better or worse, wants to get to kids early, and often. Advertisers, religions, people trying to teach kids how to deal with advertisers and religions, militaries, etc... all see the value in "getting them young."
