He (the new DP of Japan leader) will take the already reeling economy of Japan and make everyone of its ailments worse, while doing so with solutions that will be promoted as saving it. When he fails, like any American liberal, he will blame others for preventing him from going far enough in his “reforms”.
The LDP is/was suffering under a huge John Maynard Keynes addiction. May we all survive long enough for history to record that the biggest villain of the 20th century was Keynes and not Hitler/Mao/Stalin.
When the LDP was courting the New Komeito party around the turn of the century to shore up their majority in the Diet, they passed a "stimulus" bill that consisted of a voucher give away to younger Japanese with children (basically the prime demographic of the Soka Gakkai) and most of the vouchers ended up being spent in hostess bars.
In 1999 they also went through the same kind of bank bailouts that the US did in late 2008 and again in 2009.
With the kind of track record the LDP has, it's not surprising that enough people finally got fed up and wanted to throw out the old.
