"I will transform England from a 'Give me everything' society into a 'Do it yourself' nation." This phrase was spoken by Margaret Thatcher in one of her campaign speeches, and once elected Prime Minister of England, she followed it as a mantra. The beginning of her term was marked by strikes, protests, and even food shortages. But Thatcher, nicknamed "The Iron Lady" by the press, remained true to her principles. Within a few years, the situation improved, and the Prime Minister managed to modernize England's productive system, reduce inflation and unemployment, cut taxes, and privatize deficit-ridden state industries. Due to the success of her government, Thatcher remained Prime Minister of the United Kingdom for 11 years before resigning. In these times when tough but necessary reforms are being discussed in Brazil, it is worth knowing the example of Margaret Thatcher's leadership, a prepared and determined woman who transformed her country and made history.
