What is the main idea of the news item? [br] [originaltext] The nurses came

The nurses came from across the United States to Wall Street to lead a national organized labor movement against what they consider the inequities of Wall Street traders and banks. They are advocating a new fee on financial transactions that they say should be used for health care, jobs, national infrastructure and education.
    National Nurses United Executive Director Rose Ann DeMoro says such a tax could raise $ 350 billion—money, she says, belongs to the people. One of the nurses union co-directors, Deborah Burger, says it is time to share.
    Why are the nurses taking the lead in this transaction tax proposal? Diane Brady, senior editor of the magazine Bloomberg-Businessweek, has written about the nurses’ movement. Brady says Sweden and Japan had to ditch such a tax after a few years. She says the reality is that financial products more than any other products in the world are mobile, so if you add a tax in one jurisdiction all the trades will go somewhere else.
    New York University business and economics professor Joe Foudy says such a proposal has also come up in Congress during the past two years, but it is dead in the water. Foudy adds there is a huge disconnect between the culture of Wall Street and the rest of the country. The rest of the country looks at Wall Street as having helped to create the financial crisis in the United States, while people on Wall Street view this as, "It was someone who had my job four years ago and it is not my problem." And he believes there will be rising popular anger as long as the disconnect is there.
