Color me fucking SHOCKED!
There's more and more people realizing every day that this government is leading the country into the toilet. All of those workers (well, at least most of them) ALL voted for Chávez every chance they got, and most likely for Maduro as well back in April 2013, and now they are protesting and demanding what's their right, and what do they get? Gunfire from the oh-so-virtuous Guardia Nacional Bolivariana.
The shit's starting to hit the fan for Maduro and co. The situation in the country as a whole is getting out of control. The most recent polls say it, more than 60% of the country thinks Venezuela is in bad shape, and most of those people believe Maduro and/or the Ministers are the main cause of the problem. It's gonna be entertaining to see how these corrupt assholes try to maintain the status quo when the next devaluation is announced and the gas prices are raised. In the end, it's the most humble folks who will be affect by these measures, not those in the middle class or above. And those humble folks are (well, at this point, USED to be) the ones who voted most fervently for chavismo. I've actually been reading up in a lot of chavista sites, such as Aporrea, and more and more writers are starting to realize and admit that Maduro and co. are just not doing what's necessary to keep the country from ruin.
