I feel like adding some of my posts on the nationalisation / privatisation thread on this one!

But, no matter what people think about that topic, in answer to your very interesting appraisal, I personally reckon all the time there is mankind, the desire to make profit will drive capitalism forward. Even the Chinese, after the Russians, have joined this club as until a better system is discovered then capitalism will rule.
Dodgy things have always happened in 'the City', and I only have to think of the railway magnet George Hudson who committed fraud in his investments within the Midland Railway during the railway mania of the 1840s, and was disgraced by the bubble bursting in 1845. He actually remained a Conservative MP until 1859. Before that there had been the South Sea Bubble that had burst for investors around 1720 with many ruined. These scandals, amongst many, have rocked 'the City' for a long time, and I just do not foresee a collapse of confidence in it any time soon over a few bad banking decisions.
Capitalism lives! 8-) 8-) 8-)
