Pope denounces 'throwaway' culture of consumer society

SANTA CRUZ, Bolivia -- Pope Francis denounced the "throwaway" culture of today's society that discards anyone who is unproductive as he celebrated his first public Mass in Bolivia on Thursday, one of the key days of his South American pilgrimage.

It was to culminate with a summit of farmers, fishermen and indigenous whose causes have long been championed by history's first Latin American pope.

The government declared a national holiday so workers and students could attend the Mass, which featured prayers in Guarani and Aimara, two of Bolivia's indigenous languages, and an altar carved from wood by artisans of the Chiquitano people.

In a blending of the native and new, the famously unpretentious pope changed into his vestments for the Mass in a nearby Burger King.

Speaking to the crowd in South America's poorest country, Francis decried the prevailing mentality of the world economy in which so many people are "discarded" today -- the poor, the elderly, those who are unproductive.

"It is a mentality in which everything has a price, everything can be bought, everything is negotiable," he said. "This way of thinking has room only for a select few, while it discards all those who are unproductive."

It's a theme he was expected to expand on later in the day at the summit of "popular movements," a collection of non-governmental organizations representing street sellers, indigenous groups, mining cooperatives and "cartoneros," who sift through garbage looking for recyclable goods.

His keynote speech was expected to be one of the highlights of the trip, outlining some of his core priorities about a church that cares most for the poor and marginalized.

When Francis headlined the first such summit at the Vatican last October, he issued an off-the-cuff monologue on the injustice of unemployment, the scandal of poverty and the obligation to care for the Earth.

"Tierra, Techo, Trabajo," was his mantra then. "Land, Lodging, Labor."

The scene in Santa Cruz's Christ the Redeemer plaza was festive, with street-sellers hawking digital watches with the pope's face on them and indigenous in feathered headdresses mingling with mestizos, or Bolivians of mixed indigenous-Spanish ancestry.
