Add the government "healthcare" to the mix and you might see a trend in what happens when the government runs "businesses". I was glad to hear Romney speak what had been reserved for Conservative pundits: The government doesn't run anything as cheaply or efficiently as the Private Sector...
Just in case you thought otherwise, perhaps it should be made clear that government doesn't run power generation in Britain...hasn't done since Thatcher privatised the industry in the 1980s.
