I've been following the political situation in Venezuela for a long while (political geek and it interests me) - my Spanish isn't up to scratch so translations and English Language websites have been my sources.
While I'm no fan of socialism, its more of a failed petro-state with hyper partisan politics, an unbelievably stupid government and an opposition that couldn't plan their way out of a paper bag. They have price controls and done a bit of expropriation, but they're nowhere near places like Cuba. They've tried the one party state thing but even on the left there are many factions - while the PSUV (the governing party) have pulled tricks (an example from a Chavez supporting website
https://venezuelanalysis.com/news/13882) they don't have single domination even on the left, with the Communists and various communes winning elections against the PSUV (that is when the results are not stolen away from them).
Probably the most egregious anti-democratic things to happen in recent years was the National Constituent Assembly taking over day to day running of things from the Congress thanks to a dodgy supreme court decision (packed with Chavista loyalists) and a bizarre interpretation of the constitution; and the government distributing food parcels via their local party infrastructure (called CLAPs) rather than via the state. Want to eat and you're living in a poor barrio? Best not be known as an opposition supporter!
The opposition are a complete bunch of jokers. They've refused to participate in recent elections (national constituent assembly elections, then municipalities, then governorships, then the presenidential elections in May last year). They had the PSUV on the run in 2013, with the loss of congress then the guarimbas (huge street protests), they fell about arguing and eventually decided on mostly withdrawing from the political scene, allowing the PSUV with win election after election even though citizens were pretty hacked off with the government. My guess is that lots of venezuelans can't stand either side, stuck between an incompetent government and an opposition likely to be just as useless if they get in power.
All in all, I can't see a good solution available.
