Alex Cole-Hamilton mentioned the training of doctors of all sorts. In order to prevent the drift of newly qualified doctors to Australia, Canada and the USA after the state has invested £250,000, on average, in their training, would it not be worth considering the introduction of a bond system whereby, if people chose to work in other countries just after the state had paid for their expensive education, they would be required, over time, to pay back at least a proportion—or all—of the costs of their training, which would be benefiting another country?
