Yes, there were loans.
If you cosgin my mortgage and I pay the mortgage on time, does that mean that you were not liable?
I'm liable if you don't pay.
The banks paid back the loans. The Treasury will actually see a profit on the bank loans.
So how are taxpayers liable?
Right, and if you co-sign my mortgage, you are running the risk that I won't pay, which is why if I asked you to co-sign my mortgage you would say no. The fact that the banks were able to pay back the loans this time does not mean that they will next time. In fact, they will likely be even more reckless in the future because now they know for sure that there are people like you out there who are happy with them all making a fortune taking excess risks and then running to you when things go bad.
