too much capital stuck in USD cash. which idle capital. as far as i'm concern, these gov'ts will kep interest rates at 1% until the economies improves or pump up cash into the economy and get som inflation just to get the economy going if they are force to. so two years of 1% on cash basically cash can be making nothing in interest. that is what you call unproductive capital when you no returns on capital. right now the US has 1 trillion in defict, 1 TRILLION deficit.....that new money will be circulating in the economy.
