“One of the problems that the government's economic and incentive policy scheme had through the missions was that people stayed at home and did not look for work, it was easier to get a government stipend than to go out to look work... and get ready for work."
In January 2017, while Guerra is a deputy, a new president of the Central Bank of Venezuela is appointed on what he said:
" Sanguino is a person who has no notions of what a Central Bank is. He is an economist graduated in the 60s where modern things in the economy; monetary theory, fiscal theory; they were not developed... he is a man who has never dedicated himself to the economy itself. Get yourself! On Google a Sanguino writing... a book, a papper or an article related to the economy... a 140-character tweet, you won't find it... he has an archaic vision of what inflation is, he believes that inflation is that some types sell expensive... he has an aversion to the financial system, he is not a man of dialogue with the financial sector... what we are going to see is Good financing... flooding the economy of worthless bills. Sanguino could do that work of reason... to finish purging, according to them the most technical elements, what they call neoliberal."
«The measures were taken on Friday, but the situation in Venezuela was already very precarious before the measures. So what we are living now have nothing to do with the measures... the main impact of the measure is that new debt cannot be placed in the United States or with companies in the United States; What hinders the financing of PDVSA... the problem is that given the macroeconomic conditions of Venezuela and given the risk country Venezuela does not have access to world markets... it is not that the country is blocked is that domestic economic policies led to country this isolation and confinement this has nothing to do with the Assembly to block the government, is a self - locking is a self inflicted by an erratic economic policies harm."
