Originally posted by Nesster They also flooded Western markets with cheap goods, driving down goods inflation. Western central banks -- in thrall to inflation-targeting -- cut short-term interest rates ever lower. They set the price of credit too low, forcing pension funds and insurers to hunt frantically for yield to match their books. The central banks compounded the effect.
Western multinationals played their part in this saga. They drove up the profit share of GDP to historic highs, playing off wage rates in the US and Europe against cheaper labour in China, Latin America, or Eastern Europe. That too concentrated wealth among those who tend to buy shares, land, and Impressionist paintings, rather than goods. The GINI coefficient of income inequality went through the roof, as it did in the late 1920s. It is a formula for asset bubbles.
And these two paragraphs pretty much nail the supply side economics - all that wealth accumulating has no place to go, so it (and the pension funds etc) start to speculate. And corporations just jack up profits rather than tending their consumers/laborers.
Like government spending, who saves and how makes a difference.
