In Germany we have the same situation. I guess the people here spend (or better invest) thier money into propertys, shares, gold or even pinballs, because you get nothing for your savings. In some cases the people have to pay for leaving the savings on the bank account.
If you need money, you get it really cheap from the bank.
Im sure we are building bubbles.
The result of cheap money are high prices, for propertys and pinballs...
On the other hand, the people who have pinballs for sale trying to get a piece of the cake.
Happy selling!
