Well the point of that is to affect NPV of money right and force investment. And corporations go meh, too much risk. I think that's what's happening. I think even the negative interest rate isn't going to make them budge because the profit margins are razor thin, and even if you make something doesn't mean it will all not be wasted. The economy is saturated and the corps don't know how to make profit in it so they rather sit around and do nothing, and let China and other countries produce everything and then try to be the middle man or something as such with minimal risk and investment.

ex. of stuff corps are trying to get those profit margins http://imgur.com/9P9vT5r
