It all started with the President Hugo Chavez and the expropriations,

I suspect it started before that, with the people being smitten with socialist slogans and choosing socialism as an economic and political model for the country.

Released from prison after two years, he founded a political party known as the Fifth Republic Movement and was elected president of Venezuela in 1998. He was re-elected in 2000 and again in 2006 with over 60% of the votes. After winning his fourth term as president in the October 2012 presidential election,[2] he was to be sworn in on 10 January 2013, but Venezuela's National Assembly postponed the inauguration to allow him time to recover from medical treatment

Who voted for him and his policies, was it not the same people? I wonder if people understand they play a role in all this mess, rather than blaming a single person?
