I wrote about this about 5 weeks ago: do gooders had shutdown the American horse slaughter industry, and the response of cash strapped horse owners was to starve their animals.
Let me clue you in: your noble desire is for the horseowner to buy a bundled good — euthansia and disposal. In managerial economics we point out that unbundling bundles that make them unhappy is a standard way for consumers to trip up clueless management. So you need to ask yourself if you’re comfortable with owners choosing the “starve and dispose” bundle when they find out it’s cheaper.
Hurray for President Obama.
