Someone has advised me not to feel guilty by living in Britain. Here is an answer:

"I was in the Indian Police five years, and by the end of that time I hated the imperialism I was serving with bitterness which I probably cannot make clear. In the free air of England that kind of thing is not fully intelligible. In order to hate imperialism you have got to be part of it." — George Orwell, The Road to Wigan Pier

Orwell had his reasons at the time. I have my different reasons today. The fundamental remains: Britain is an imperialist state and I am part of it.
