To sum up :
- Subprime crisis + Deregulation since Clinton's era makes all bank go near bankruptcy
- Banks whine to death and asks states to give them cash so they don't die
- All states boast on bailout plan by giving multibajillon to bank's pockets to 'save economy'... without any compensation, and thus raising their own deficit
- Banks makes money by speculating on states' debts
- Banks pays back the states and the interests in less than two years, without a thanks
- Banks can now makes moar money with the aid of notation agency saying : 'oh, this state is in deficit, let's pwn them'
tl;dr version :
Bank's deficit is now states' deficit. => You pay. End of story.
