whomever is profiting will just rig the metric.

Not having a metric set out in advance may, in fact, be more rigging resistant! unfortunately.

But the real deal is that none of it matters because the program itself is the goat sacrifice. It's not there to work, it's there to signal the proponents values and ingratiate themselves with the goat suppliers. It's actually better for theses purposes if it DOESNT work, because then you can perpetually campaign on solving the same problem and conserve the considerable effort that went into convincing people that the problem exists and needs solving.
