I disagree about the civic education. Everyone knows the IRS doesn't take gift cards, it's more about taking advantage of people when they have a panic response. You get a call from the government saying you're going to jail if you don't pay them right now, you may panic. If you panic, what are the odds that you're going to get yourself under control before you do something stupid?
I've seen this happen to a very bright coworker of mine, it's all about taking advantage of human fear.
