Voilà ce qu'on trouve sur Wikipedia au sujet de Tina.:  In economics, politics, and political economy, the acronym TINA refers to a slogan attributed to Margaret Thatcher, once prime minister of Britain, i.e., that "There Is No Alternative" to global free-market capitalism. This is the central slogan of economic liberalism, arguing that free markets, free trade, and capitalist globalization are the only way in which modern societies can go.
Susan George, a prominent critic of neoliberal globalization disagrees by saying "TATA!" (There Are Thousands of Alternatives), which also refers to the main political slogan of the alter-globalization movement: "another world is possible".
