Paul Craig Roberts and Nomi Prins see the Libor interest rate manipulation scandal a bit differently:
According to news reports, UK banks fixed the London interbank borrowing rate (Libor) with the complicity of the Bank of England (UK central bank) at a low rate in order to obtain a cheap borrowing cost. The way this scandal is playing out is 
that the banks benefitted from borrowing at these low rates. Whereas this is true, it also strikes us as simplistic and as a diversion from the deeper, darker scandal. Banks are not the only beneficiaries of lower Libor rates. Debtors (and investors) whose floating or variable rate loans are pegged in some way to Libor also benefit. One could argue that by fixing the rate low, the banks were cheating themselves out of interest income, because the effect of the low Libor rate is to lower the interest rate on customer loans, such as variable rate mortgages that banks possess in their portfolios. But the banks did not fix the Libor rate with their customers in mind. Instead, the fixed Libor rate enabled them to improve their balance sheets, as well as help to perpetuate the regime of low interest rates. The last thing the banks want is a rise in interest rates that would drive down the values of their holdings and reveal large losses masked by rigged interest rates.
Briefly put, the Libor scandal is the result of a smoke and mirrors operation meant to secure the smoke and mirrors world of high level banking.
