I don't think he is suggesting that. The fact is that many people under 40 are priced out of the market. 20 years ago, a graduate could easily buy a flat or house, rates of owner occupation were higher, and we still had the option to rent. This tended to suit people at the start of their careers, when they were more likely to move for work. After a certain age, you start wanting to settle somewhere.
