Famous quotes containing the word status:

    At all events, as she, Ulster, cannot have the status quo, nothing remains for her but complete union or the most extreme form of Home Rule; that is, separation from both England and Ireland.
    George Bernard Shaw (1856–1950)

    [In early adolescence] she becomes acutely aware of herself as a being perceived by others, judged by others, though she herself is the harshest judge, quick to list her physical flaws, quick to undervalue and under-rate herself not only in terms of physical appearance but across a wide range of talents, capacities and even social status, whereas boys of the same age will cite their abilities, their talents and their social status pretty accurately.
    Terri Apter (20th century)

    The influx of women into paid work and her increased power raise a woman’s aspirations and hopes for equal treatment at home. Her lower wage and status at work and the threat of divorce reduce what she presses for and actually expects.
    Arlie Hochschild (20th century)
