Venezuela is a typical Latin American country with a history rich in political unrest, systemic poverty, and strong-arm authoritarians in positions of power.
I don't see much changing positively out of some revolution. Maduro banned a presidential candidate recently, he may be planning on rigging the 2018 (19?) election.
If Maduro were assassinated or dropped dead the situation would likely only worsen as there would be a power vacuum and surely some attempt to gain power through violence while claiming to be liberating Venezuela from a failed democracy.
Pretty much the only reason Venezuela was ever relevant was because their oil. You can't eat oil.
I think you're wrong. Saudi Arabia is also living through the sale of oil but there all the people are rich. The regime in Saudi Arabia is also an autocratic. Probably another reason. In Venezuela the power thieves. That's the whole reason.
The difference is easy to spot.
Saudi Arabia welcomes foreign investors while Venezuela wants to nationalize everything.
Saudi Arabia is investing in infrastructure and technology while Venezuela is investing is socialism giving money for being lazy.
Outcome was pretty clear from years ago
