This Craigslist poster has the right idea: donate your persistent vegetative state in advance to be cynically manipulated for the cause of your choice.
If I am rendered comatose and determined to be in a persistent vegetative state (PVS) for a period longer than one month and if no imminent cure is forthcoming, I do not wish to be kept alive by artificial means including but not limited to nourishment, hydration, etc.
However….
If, due to the absurd political state of affairs in this country, my persistent vegetative state and impending unplugging can be parlayed into some sort of political leverage, I wholly endorse using my predicament in whatever way possible for the purposes of passing legislation favorable to my general political and ethical outlook. Here is a list of top-tier causes I support and will continue to support, both while in my PVS and after my eventual death.
* Debt Relief to Impoverished Nations: I will agree to stay in a PVS for an indeterminate amount of time if the United States aggressively pursues a policy of debt relief and debt forgiveness to developing and impoverished nations.
* Nuclear Disarmament and De-escalation: I will agree to stay in a PVS for a open-ended period of time if the United States aggressively pursues a policy of nuclear disarmament and de-escalation. By this I mean desisting from developing new bellicose nuclear technologies and providing significant non-military incentives for nations to avoid nuclear armament.
