There were three men on a sinking boat.

The first said, "We need to start patching the boat else we are going to drown. We should all bail and patch."

The second said, "We will run out of water in ten days, if we don't make land fall. We need to man the rigging and plot a course."

The third said, "We should try and build a more sea worthy ship. One that wasn't leaking and had more room for provisions, then we wouldn't have had this problem in the first place. It also needs to be giant squid proof."

All three views are useful, however the amount of work that we need on each is dependent on their respective possibility. As far as I am concerned the world doesn't have enough people working on the second view.
