The Wikipedia Arab Spring article gives information this event.
In recent decades rising living standards and literacy rates, as well as the increased availability of higher education, have resulted in an improved human development index in the affected countries. The tension between rising aspirations and a lack of government reform may have been a contributing factor in all of the protests. Many of the internet-savvy youth of these countries have studied in the West, where autocrats and absolute monarchies are considered anachronisms. A university professor of Oman, Al-Najma Zidjaly referred to this upheaval as youthquake.
Tunisia and Egypt, the first to witness major uprisings, differ from other North African and Middle Eastern nations such as Algeria and Libya in that they lack significant oil revenue, and were thus unable to make concessions to calm the masses. “
This Wikipedia Occupy Wall Street Article discusses this event.
“BackgroundAfter the late-2000s recession that left many countries on the edge of bankruptcy, with weakened economies and unemployment at very high levels, a Canadian-based group, the Adbusters Media Foundation, best known for its advertisement-free anti-consumerist magazine called Adbusters, proposed a peaceful occupation of Wall Street in protest against the current U.S. political leadership and the failure to prevent or make effective changes regarding the global financial crisis. According to the senior editor of the magazine, “[they] basically floated the idea in mid-July into our [email list] and it was spontaneously taken up by all the people of the world, it just kind of snowballed from there.”
Although it was originally proposed by Adbusters magazine, the demonstration is leaderless. Activists from Anonymous encouraged its followers to take part in the protest, which increased the attention it received. Other groups followed, including the NYC General Assembly and U.S. Day of Rage. The protests have brought together people of many political positions.
Prior to the protest's beginning on September 17, New York City mayor Michael Bloomberg said in a press conference, "People have a right to protest, and if they want to protest, we'll be happy to make sure they have locations to do it." “
