Most people are unaware that following Chavez' inauguration, Venezuela's income rose fourfold. Since this income from their nation's resources had previously been profit for rich investors in the industry, it is quite obvious why multiple assassination attempts (and perhaps a successful one against Chavez), sanctions, and now a devious coup is being undertaken.
'Socialism has never been tried in Venezuela' sounds like a justification or rationalization of failure of a system that cannot work, but given the active full spectrum assault on a sovereign nation, it is hard to imagine any possible system of government could have been considered fully functional.
