Right now, the world is making all the stuff people need and then some. Poverty and hunger, in the 21st century, are distribution problems. (And, inevitably, politics problems.)

Now, it's true that what people want exceeds what they need (almost by definition). But it doesn't exceed it by so many orders of magnitude that we're that far off from being able to produce it with what we have today.
