Actually, there is no evidence of this. See this report that compares the Govt run industries before and after privatisation: http://www.psiru.org/reports/public-and-private-sector-effic...
"The results are remarkably consistent across all sectors and all forms of privatisation and outsourcing: there is no empirical evidence that the private sector is intrinsically more efficient"
Even if it was more efficient, $31 billion of corrupt bonuses on top = no different from an inefficient government.
