"But he urged people to be optimistic, pointing to growing trade with India and China, and warned that pessimism and fear "can become self-fulfilling prophecies".

My notes
Nice work from Cameron mi.
UK Conservative-led government pursues infrastructure projects. None of the political dogmas to prevent action. So UK gets to climb out of hole - tries austerity and finds little growth - now tries long term government projects.
Clegg acknowledges Keynesian-type multiplier.
