"they have actually suffered from ten-year rock-bottom savings rates)"

I am more than happy to have rock bottom savings rates if it saves younger house owners from the horror of 13%+ mortgage rates that I and many others had to put up with for a period.
Also If you look at historical exchange rates since the euro was introduced stability has not really occurred, volatility is the name of the game. Historic lows occurred in 2009 that have not yet been equalled. All those currency traders hate stability, it must erode their margins.
