been mobilizing in favor of autonomy. Important issues were opposition to the seizure of resources though nationalization, the confiscation of land from local control by outside ethnic groups (mainly the Aymara and Quechua), and a greater share of taxes collected within Santa Cruz to support roads and schools. Community leaders are supported by the Comite Pro Santa Cruz, local co-ops, and by business organizations such as cattle ranchers and farmers. A strike against the new constitution was recently held which was observed in Santa Cruz, Beni, Tarija, and Pando. Tensions have been raised by the cultural and philosophical rift exposed by the push for a new constitution. As a basis for a new constitution, the western, Altiplano-based MAS party envisions a "council of indigenous peoples" along with a curtailment of private ownership, while Santa Cruz looks to western culture and capitalism. Cultural divisions exist because people in eastern Bolivia, called "Cambas" (meaning "friends" in Guarani), are primarily of mestizo descent (mix of European and several native tribes the largest of which are the Guaraní), while the western Altiplano is dominated by a small white elite and a historically oppressed Quechua and Aymara majority. The first signs of the modern autonomy movement occurred in 2005 when a march for autonomy was attended by hundreds of thousands of people. A result of this was the change in law to allow the election of departmental prefects. Another area of tension was the result of ongoing population shifts and the resulting demands for proportionally greater representation in Bolivia's Congress to reflect these shifts by Santa Cruz. A compromise was reached to allow Santa Cruz to receive some of the seats warranted by population growth, and for the highlands to keep seats despite population losses. Left-wing intellectuals Walter Chávez and Álvaro García Linera (former Bolivian Vice President and MAS party member) published an article in the Monthly Review asserting that autonomy has been historically a demand of the Santa Cruz region, "contemporarily imbued with far-right, populist sentiments." They also qualified Santa Cruz autonomy as a "bourgeois ideology" of the "free market, foreign investment, racism, etc.", which pits the "modern", "whiter" Santa Cruz elite against the short, dark-skinned and anti-capitalist Aymara and Quechua peoples of the western region of Bolivia.
