Read the whole interview, but here are two excerpts

One of the contradictions you focus on is that between the use and exchange value of a commodity. Why is this contradiction so fundamental to capitalism, and why do you use housing to illustrate it?

All commodities have to be understood as having a use value and exchange value. If I have a steak the use value is that I can eat it and the exchange value is how much I had to pay for it.

But housing is very interesting in this way because as a use value you can understand it as shelter, privacy, a world of affective relations with people, a big list of things you use a house for. But then there is the question of how you get the house. At one time houses were built by people themselves and there was no exchange value at all. Then from the 18th century onwards you got speculative house building – Georgian terraces which were built and sold later on. Then houses became exchange values for consumers in the form of saving. If I buy a house and I pay down the mortgage on it, I can end up owning the house. So I have an asset. I therefore become very concerned about the nature of the asset. This generates interesting politics – ‘not in my backyard’, ‘I don’t want people moving in next door who don’t look like me’. So you start to get segregation in housing markets because people want to protect the value of their savings.
