So, let's be honest, Thanksgiving is a holiday for the privileged.
We (and yes, I'm certainly speaking as a member of the privileged class) take a day to thank God for our blessing and that we're not one of those others. OK, maybe we don't actually say that last part, but come on, we're all thinking it. From our privileged position of relative plenty, it's easy to say things like "Be grateful for what you have" and as Christians, "Thank God for the blessings that He's given us," but I can't help but wonder if we would be so thankful if things were reversed and we were stripped of our privilege.
Would we still be so gracious in our giving of thanks? Would we still be so certain that the way in which God had chosen to distribute His blessing to the world was "fair" and "just"?
I'm guessing no, but I've been wrong before. A lot. The interesting thing though, is that I might get to see the answer to this question in my lifetime, as demographic realities in the West begin to dismantle and rebuild our societies.
