It might not be possible to spend this amount of money for one simple reason. Germany has a so called “debt break” which means, that, in theory, Germany isn’t allowed to increase its debt. This is written in the construction, so to change this you need 2/3 of the parliament to agree. Now comes the real problem, our leftist party and the AfD make up over 2/3 of the parliament so it isn’t possible without them and both parties don’t want to increase military spending.

These mails probably were sent automatically without checking how much the artists owed. So it isn’t really that they need that money but that they just sent this to everyone.
