No, I would say it's a matter that's just much more empirically difficult. You don't sit with the same sort of accounting instruments and the same simple or narrow approach to answering that question.
I'm not trying to say this to be provocative, but if you think about the advanced research that's undertaken, some of these things appear to be small sums, and if you just evaluate it on a dollar return to the party that's granting the funding, you're not going to find a justification for it. The idea to fund folks to create the Internet probably didn't look like good business, but it is the underpinning of global growth, and we now all benefit from it, including all the private sector that's flourished.
I would say the kind of investment in R and D and support that we're talking about is the type that has that long-term benefit, but again, it's not evaluated in the same way. I think we have to rely on evidence about the effects of these kinds of initiatives, the effect of supporting, in a direct or indirect way, business activity, if it has a public benefit, and determine that from research rather than each specific deal.
