That is some bit of revisionist history you have going on there....But in the end I agree it is up to the people.Listen.. yes people voted for Chavez, and they got what they got. Point is that they voted for him because the largely conservative right wing parties had abandoned them. And "them" are the majority of Venezuelans. Now had the largely conservative right wing parties not been utterly corrupt to big business and the elite 1%, and actually represented the people when in power.. then there would have been no overreaction aka moving to Chavez.
Also it does not help that these same right wing forces in Venezuela then try to remove Chavez via a coup and by all accounts these coup makers were very much supported by the US. Now even if it was not true (it was of course at least partly true), the damage is done because of the accusation and the fact that the US has done similar before in multiple countries in Central and South America. All the failed coup did was to embolden the majority downtrodden masses that vote for Chavez and his party. It gave Chavez and his people the excuse to hit down on the opposition and media outlets..
In the end it is the people of Venezuela that have to do the change and move more towards the centre, but as it stands now that wont happen. What we see in Venezuela has quite a few similarities to other countries where the elected governments were undermined by right wing opposition and the US and I have no doubt that Chavez's side will exploit that for now, regardless if it is true or not. It is what they are doing now. The idea of putting guards in supermarkets to prevent price gauging is the first step in nationalizing the whole thing.. why? Because those supermarkets are owned by the 1%, and have deep links to the right wing political parties and governments of the past. It is the same thing he did towards the media.
As I see it, the only thing that can change Venezuela is if the military steps in and removes Maduro... unlike Chavez he aint a military man and the chaos in the country can get so bad that they feel compelled to step in. This will of course start a civil war.
