Tracy: I'd like to think of myself as a rocket launcher, but that time has yet to come.
Tracy: GDP is nothing more than a measure of annual financial transactions, with no distinction between positive and negative transactions. This means that GDP increases with more crime (more prisons have to be built), more water pollution (more bottled water is sold) and more cancer (more drugs are sold). In this way of measuring progress, land-based, relatively self-sufficient communities, who by their very nature do not generate many financial transactions, are considered poor and backward.
Tracy: People in the West are only told the third world is extremely poor. In fact, fifty percent still live on the land, where many are free to build their own homes without debt, grow and eat their own food, and have extended families and supportive communities.
Tracy: ( of her modelling career) I felt like a walking coathanger. I found it extremely boring and pointless.
Tracy: Although there are some brave politicians who are prepared to risk something, most of them keep behind the party lines and are bent on the never-ending, short-term task of winning votes.
Tracy: Economics has turned into a giant casino and con game.
Tracy: In this country, there is little difference between the main political parties - they are all selling the corporate agenda. They see the public as consumers who will keep the economy growing and bankers happy.
Tracy: We may not be able to turn the clock back, but we can change direction.
Tracy: My idealism either inspires or frustrates.
Tracy: I guess I could best be described as a networker - making connections between people and getting them around the same table.
Tracy: ( on the name Tracy) People do prejudge me because of my name, but a few minutes after meeting me they will either keep that prejudgement or drop it.
Tracy: (of her early years) It was a comfortable childhood, though I was really brought up by a nanny. My parents lived in London and I saw them about twice a month when they came down to the country.
Tracy: I am not a celebrity, but I am married to an aristocrat, which means I'm also supposed to be grateful and grin a lot. But I don't, I bang on about ecology because the hand that feeds all of us aristo-celebs also doubles as a fist that is demolishing the planet and its people for the sake of short-term profit. I am therefore known to all and sundry as The Mad Marchioness, the Whacko Worcester. That's why I'm not grinning, I'm snarling! (from 'The New Statesman' magazine, December 1999)
