In reply to neilh:
....I don't want to live in a country with 33 million and counting, cars driving around.
We need system change.
As an example........blackberries from China, apples from New Zealand could be replaced by produce grown in market gardens on the edge of villages/towns and cities. Straight away, the demand for infrastructure would be reduced, and intrinsically interesting jobs created. People could walk to work. Physical and mental health improved. The collective brain could think of all sorts of small/big changes that would bring these benefits. It would need/involve greater equality which I think is essential to make progress, and to make us all happier. We would end up closing roads and reducing timetables because the need to travel would be reduced. GDP would fall but we could start measuring success in different ways.
Of course I'm dreaming........
