the changes. The two decrees in particular sparked protest: a law aimed at strengthening government control over the oil company PDVSA and a more controversial land reform law, which included provisions for the expropriation of "idle" lands. Though the government stated that it would provide the previous owners with compensation at the going market rates, the land laws introduced by Chávez were so vaguely worded that the government could legally expropriate any property it wished to take. While some of the land was genuinely given to the vulnerable, much of it was used in a system of patronage for party members loyal to Chávez. McCaughan described the 49 laws as the "plus ultra non", the "point of no return for Chávez's troubled relations with business, church and media leaders". For the opposition, such dramatic changes to the government proved to them that Chávez was a "dictator-in-training". On 10 December 2001, a national strike shut down 90% of the economy and was the largest strike in Venezuela's history, bigger than the strike that assisted with ending the dictatorship of Marcos Pérez Jiménez in 1958. By January 2002, protests involving hundreds of thousands of Venezuelans opposing Chávez became common in Venezuela. Petróleos de Venezuela (PDVSA) In March 2002, Petróleos de Venezuela (PDVSA), the state oil company that acted autonomously and accounted for 70% of Venezuela's foreign revenue, was targeted by Chávez out of fear of the oppositions ability to call national strikes and was to receive strict control from the government. Chávez's attempts to end the functional independence of PDVSA were met with strong resistance from PDVSA officials and managers. On 7 April, Chávez fired the President of PDVSA, Brigadier-General Guaicaipuro Lameda Montero and replaced him with a former Communist Party militant, in addition to firing another 5 of the 7 members of the PDVSA board of directors on his Aló Presidente program, mocking each worker by name and used a referee whistle, as if to expel them from a soccer match. Such actions by Chávez caused further opposition developments with a series of walkouts and work slowdowns followed. The Washington Times then noted that Chávez had "choked off foreign investment by doubling the royalty payments oil companies must pay to the government and by restricting corporate ownership on some oil projects to 49 percent", and had "alienated workers at his country's state-owned oil company, Petroleos de Venezuela, by replacing long-serving professionals
