My Lords, this is, I am afraid, an idea that probably looks good in the confines of the Treasury or in the rarefied world of special advisers in No. 10. In the real world outside it does not look so good. The noble Lord, Lord Kerslake, mentioned the late Bob Crow. I recognise, as the noble Lord said, that there is a case for saying that people on a higher income or earning over £100,000 should move out of council tenancy and seek a home of their own, thus leaving one for someone on the waiting list. I understand that argument. It is an important one that we should not forget.
However, this is not the greatest problem that we face. In the case of London, for example, where the housing crisis is most acute, 100,000 properties have been bought by secret offshore companies, pushing prices up for ordinary Londoners, who cannot get access in the way that they need to. I also agree with the noble Lord, Lord Kerslake, that this leads to a lot of administration for a small return. He used the word “inefficient”; we should not compromise on efficiency in administration. I believe in smart government, neither large, nor small; it depends on what you need. We should have efficient government and this in principle does not look like that. A lot of bureaucracy will be involved, a lot of mistakes will probably be made and the returns will be quite small. Should the Government be doing something as detailed as this? Should they not leave it to local government? Frankly, this smacks of the sort of thinking that went into the bedroom tax, which I think that many people regret.
While my noble friend Lady Williams has noticeably been listening throughout—I pay tribute to her conscientiousness and her willingness to take arguments on board—there is a case to be made for Amendment 72, which would leave this matter to the local authorities. I agree with the noble Lord, Lord Kerslake, that we need a higher threshold before it kicks in: £60,000 in London and £40,000 outside are a minimum, frankly.
In many ways I would prefer a higher threshold, but that would be a starting point, which is encapsulated in Amendment 77 in the name of the noble Baroness, Lady Bakewell. I also agree with the proposal in Amendment 75; if the administrative costs outweigh what you raise in revenue, it is senseless to go ahead.
Finally, if we do go ahead with this and raise some money the local authorities should keep it to invest in further council housing. That is essential. It should not go into the pockets of the Treasury, which does not need this small amount and it should not get it. The amendments in this group are both fair and sensible, and it is my experience that what is fair and sensible is usually good politics.
