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

We have the most crude accounting tools. It's tragic because our accounts and our national arithmetic doesn't tell us the things that we need to know.

I was recently looking at what they can actually do to reduce consumption of petrol. It would be quite possible to build automobiles out of carbon fibre that would be just as strong, weigh 10 times less and consume 10 times less petrol.

Subsidize... or lend.

The World Development Movement, to take just one example, is doing good work. Some political parties are, too.

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.
