Environmental researcher Tony Walker: “When the cost is a disincentive to do an activity, people change their behaviour.” She was talking about reusable bags when shopping.
It’s a bit disconcerting to speak of
people—or to be spoken of—as if one were a member of an enormous flock of
sheep. It implies that reason alone won’t be enough to get individuals to break
habits, to cooperatively join in a campaign to save the planet, for instance. But
we need only look to ourselves to see how tenaciously we cling to present
patterns of behaviour, even when our reason tells us the sloppy use and
disposal of plastics, for instance, is like a poison to sea life on which so
many people depend for food.
It’s this tendency in human nature that makes Pigovian punishment/reward incentives like the carbon tax necessary. When tobacco-caused lung cancers overburdened oncological healthcare and cost thousands of lives annually, tobacco was heavily taxed, as is liquor. When I drive sparingly, car pool, park my fossil-fuel burning pick-up, my carbon tax rebate exceeds my travel costs, a Pigovian incentive reward. If I make no changes, the tax punishes.
Granted, these incentives/disincentives must be reasonably applied: until alternate energy sources reach full development, goods must be transported, people need to get to work, food must be grown using the means at hand.
Isaiah
53:6 says, “We all, like sheep, have gone astray, each of us has turned to our
own way ….” The simile is problematic given the little I know about shepherding.
The most basic impulse of sheep is to flock, to be and move with their
collective. It’s not to be individualistic, to “go each astray.” But for our
purposes, Isaiah’s point about “going our own way” becomes prophetic about the
tension between individual rights and responsibility to “the flock.”
Pigovian incentives are like
sheepdogs—to be more crass, possibly, than necessary. They bring us up short
when we “stray,” when we cater for our own pleasure and convenience without
considering the well being of our flock.
It’s no
surprise that sheep hate dogs. But a seasoned shepherd will tell you that
without them, it’s not the “each straying” that poses the greatest danger, but the
destruction of the entire flock if it should follow an “each” over a cliff.
