Throwing rocks at rescued miners

Whoa. Chile's economy has been growing, it's stock market has been one of the better performers since 2009. How to explain this story except by social mood?

Protesters throw fruit at Chile’s rescued miners

It has been a bittersweet anniversary for Chile’s rescued miners, who were honored as heroes in their home town only to come under attack by anti-government protesters who threw fruit and small stones at them, accusing them of being ungrateful, greedy sellouts.

...But the events were marred by scuffles between riot police and protesting students, teachers, environmentalists and other miners, all trying to pressure Pinera to accede to their demands on reforming public education, increasing miners’ pay and stopping controversial dams and power plants.

Throwing rocks at the miners is partly explained by what sounds like the leftist makeup of the protest. Spitting on soldiers or throwing rocks at people trapped underground for 69 days is OK in the advance of politics. But still, the greater story is the shift in social mood, how else to explain the large drop in the president's popularity?

Pinera’s popularity has plunged to 26 percent, the lowest of any president since Chile recovered its democracy in 1990, as protests have roiled the country. Environmentalists hope to block hydroelectric dams in southern Patagonia and a huge coal-fired power plant in northern Chile. Unionized miners have briefly paralyzed the nation’s largest copper mines, costing companies millions in lost production. Mapuche Indians have occupied ancestral lands, setting off violent confrontations with police and landowners. Striking high school and university students have stopped classes for more than two months.
