The "Economic" Draft: Coercion vs. Persuasion

Tom Palmer has a recent reference on his blog to a group that says raising the pay for soldiers is economic conscription.
I see -- by offering potential soldiers more money, the gubmnt is forcing them to give up their next best alternative?

I guess the process of meeting or exceeding soldiers' opportunity costs and thus generating supplier surplus is equivalent, in their minds, to drafting them. What idiocy! I expect these folks don't understand the difference between "persuasion" and "coercion" as explained in The Economic Way of Thinking.

Sounds like the old Flip Wilson line: "the devil made me do it."
