This is a tough one. The killer is explaining where the money comes from without losing them trying to explain the economic model and the inflation and the reward pool distribution and...and...and...
I have tried using an analogy. Imagine you had a magazine subscription that costs $20 per year, but you could pick and choose which articles and authors you wanted to pay rather than just the whole lot.
Now imagine you put $1000 into some shares that pay a dividend at 2%pa that earns $20 each year which you use to pay your magazine subscription.
This is what it is like, you put $1000 into Steem Power and you get votes to financially reward those authors and support the content you like.

It really helps if the person in question has a solid understanding of economics. Of course, I realize that's a rather shockingly small demographic these days.
If they understand how the money supply is currently created in the West from nothing (communal inflation), then the idea of Steem should immediately seem plausible.
