I've heard it said that you shouldn't let the perfect be the enemy of the good. This is a case of saying the perfect is impossible so the good shouldn't be done either.
Obama's argument, taken to its natural conclusion is like saying that since everyone is mortal and will die eventually, medical care is completely worthless.
I actually think Obama is executing his "plan."
- Destroy the middle class
- Fund and support the Islamic Caliphate and goad it into attacking Israel
- Bring American to 3rd World Status (except for the elites in their bunkers and limos)
