Its not a coincidence that the Japanese Economy imploded around the same time. If your country has 40% of global corporate market cap value and then it drops to 8% after an asset bubble bursts, how many ambitious long term projects you can sustain drops too. The US came really close to following the same trajectory with the 2008 bubble bursting. If the banks hadn't been kept afloat and there were alternatives to Wall St a large chunk of the tech sector would have tanked or moved out. There is no global tech leadership possible, if there is no global Finance domination.
