Vince Cable comes across to me as a typical academic who is totally divorced from the real world. For him to think that simply saying that a situation should exist and Government can make it so is, in many instances, to say the least naive. To attempt to reverse employment law at the drop of a (his) hat is almost criminal.
Perhaps it is his age and background talking; if so I think he should discuss these ideas with others before broadcasting them. A little like thinking he can control executive wages in the private sector with a single word; he should consult with shareholders - they at least have power in that area.
