Did I see somewhere that for a worker earning the male median it was about £200pa? It would have to be a pretty close call on cost-benefit if £200pa could reverse an employer's decision to hire.

What annoys me about his debate is that anyone takes these business leaders seriously at all. They say that the money is best off left with them so they can be entrepreneureal with it; in fact what the public sees is excess profit used to fund excessive executive pay and bonuses.
