And you believe that, based on no data what-so-ever? ;) Right now, we spend a lot of money and get very little. If we chose to spend more rather than passively leak money, we'd at least be able to exercise some control over how it's spent, benefit from economies of scale, and so on. To be explicit, I'm drawing a distinction between efficiency of dollars and raw quantity of dollars. Given the choice between spending $250 and getting nothing versus spending $500 and receiving something of substantial value, I'd opt for the latter. And that's what the qualifier about "benefits to society overall" is about; there's more value to be had from this than some dollar amount. But if all we're thinking about is a) how many dollars it costs (and not how we're wasting money now), and b) that some small subset of people might game the system (which will always happen, regardless of counter-measures), I think that's self-defeating.
