I agree they are not all "cabs for hire". Cameron, Osborne, Gove and Clegg are certainly not corrupt.
'So given the model of the working population paying for the retired population, how do you propose it can work without extending the retirement age?'
I don't have the answers, I am not paid to look into it. But we have experts and professors and academics that could come up with a solution. We need to increase productivity. We need to give work to the young unemployed, not keep 70 years old in work. Where there's a will, there's a way. But there is no will, because the elites don't care about the ordinary people's quality of life.
