Politically it's easy to salve one's conscience, no matter that salving it rarely makes the problem go away. You join the Labour Party, write articles attacking the privileged, give the money you spend on opera tickets to homeless charities, and vow never to go to anything that can be considered elitist again.
Show me a university which is a hotbed of thin-skinned offence-taking, where every unacceptable idea is policed and every person who happens to hold one is hounded out of a job, and I will show you a university that isn't a university but an ideological prison camp and indoctrination centre.
There's a simple arithmetical logic at work. Build more unaffordable and not always architecturally sympathetic apartments, watch the rents rise, the tarts leave, the small shops, production offices and design studios close down, and hey presto, we have another fashionable London suburb indistinguishable from the rest.
To be clear, I abhor the separation wall. It is an eyesore in itself and makes tangible the failed diplomacy and cruel short-sightedness that causes such misery in the region. No Palestinian can see that wall and not wonder if the Israelis mean it to stay there forever, a constant reminder of what they never intend to change.
