I used to work a lot on food issues and every time somebody predicted that production would be inadequate they got egg on their face a year or two later.

There are a lot of people who don't contribute anything to consumption and production.

What I worry about is climate change, because that would have untold effects that we can't even measure yet.

Now we are flying off into outer space, there is no clear curb on what can be done in the name of the economy.

This erosion of the middle class is happening all over the place. The opening of a wider gap between rich and poor is always accompanied by such a process.

There is no degree of human suffering which in and of itself is going to bring about change. Only organisation can change things.

If the economy becomes disembodied from society it can only lead to disaster.
