Thanks in large part to social media sites like Twitter and Facebook, cities around the world stood together against capitalism and failed economic policies Saturday.

October 15 was designated an international day of protest, many in to show support for the Occupy Wall Street movement that has spread to a number of U.S. cities, but also to stand up for themselves in their own countries and cities.

In Costa Rica, around 200 people marched in San Jose. In Barcelona, Spain, thousands protested as part of “Movimiento de los Indignados” or “Movement of the Outraged.” And the protestors of Puerto Rico included students, teachers, housewives, and even the president of the island province’s Association of Physicians and Surgeons.

A spokesperson for the marchers of Puerto Rico said additional events are likely in the future, with some already camping out in a public park with no plan to leave anytime soon.

The #OccupyWallStreet protest has already become the U.S.’s largest protest to date, with those involved tired demanding corporations no longer be allowed to run this government.

At the dedication of the new Martin Luther King Jr. national memorial, the civil rights leader’s daughter, Rev. Bernice King, said that her father would have definitely supported the Occupy Wall Street movement.

She added that her father would have told Americans to never adjust to certain social ills, adding, “We should never adjust to the one percent controlling more than 40 percent of the wealth.”
