Hi Keith,
Yes... but this doesn't imply that it's never worth the investment to toss resources to a bunch of people as a group, even if -- on average -- it's going to be a loss: The occasional success can still make it very much worthwhile overall. Think of it as the National Science Foundation... but applied to people: Much of what the NSF funds (with taxpayer dollars) is "basic research," just trying to understand the world around us, without any specific goal in mind or a requirement to make any money on that research... yet most people are more than happy to fund them, because of the spectacular successes that occur once in a very long while.
Of course, the devil is in the details of deciding just how much tax funding entitlements should receive and how to setup the programs to at least try to optimize the results.
Oh, c'mon, how bad can they be when they *constantly* being accussed of being both too liberal *and* too conservative? :-)
