The true cause of a crisis is pumping money into institutions which should bankrupt years ago. Pumping because we were too much afraid of normal crisis back then and now we get that crisis, but multiplied by 10 in terms of impact and time period.
Crisis is good in economy. It let big, old and damaged trees to fall and to give more sun light to small healthy trees which may start to grow.
Instead of pumping money into stock market which only feeds the richest ones, we should let them bankrupt to make a space for more healthy businesses. Unfortunately people on average do not understand it and still elect interventionists. It postpones crisis, increases income gap and make crisis at the end much more damaging.
We are very close to see a bankruptcy of Italy. Then banks which bought their bonds will follow. With the Deutche Bank on top.
