despite, or even because of, these movements of people you're seeing in the streets - and they are bourgeois, that is middle class, in nature - what the united states wants in venezuela is a government that keeps the impoverished poor in order, not one that opens up opportunity for the educated to exploit them. and, they're going to be more than happy to let the maduros of the world call them imperialists and gringos, so long as the poor are kept in check, and the oil and food keeps flowing out of the colony, and into the empire.
so, there's this bourgeois analysis coming from the north arguing that the middle classes are being repressed and maduro needs to go to better open the country to exploitation. but, the americans don't want to empower the middle class in latin america, they want to keep the country under their control. and, in a society like venezuela where the poor greatly outnumber the middle class, transferring power to the bourgeoisie is just putting in place another working class uprising - it's not a sustainable outcome.
so, wherever you stand in the class war, the reality is that maduro is the preferable option, from the perspective of american imperialist ambition.
i really think this is just theatre.
