Well, here are a few observations from a lefty (as being a social democrat)
1. I hate Venezuela and it's fake ass socialism which is just semi to complete dictatorship with short term presents for the poor purely for election purposes
2. as a social democrat I can only think of 1 reason why the government takes over a company, that is when this company is of vital importance for the country and is about to collapse/go bankrupt (which could be a bank/water company/electricity company/etc.) when this company cannot function on it's own anymore and it cannot survive without huge government loans. But, just like it happened in the banking crisis in 2008, this is a temporary measure and the sales of the shares that the government acquired/took over have to be sold to the public and the money that comes from this has to be returned to the government finances.
3. General motors is a US company, Venezuela should keep it's grubby hands of private property of GM.
4. Hugo Chavez was a dictator
5. Maduro is a dictator
6. Venezuela is not a socialist nation, it is a dictatorial country
7. the sooner Venezuela is cleansed of this so-called socialist dictatorial scum, the better
8. I am also talking out of selfish reasons as part of our Kingdom is situated just a short stretch of water from Venezuela
9. Also, it is not a great plan to steal (because that is what it is) factories, it is a very stupid plan
10. There is no one "leftist" view. Some might see themselves as leftist countries (like Venezuela, China, Cuba now and in the past countries like Libya, Russia) but they are not, they are dictatorial countries who misuse a name for political power and gains.
