M-A makes a good point... nationalization and privatization have generally had little impact, because either way the resources end up in the hands of the same elite groups, who manage them for their own benefit instead of the nation's benefit. Any company that wants to be involved has to cut a deal with those same elites.

It's an ugly reality but anyone who wants to change it has to face the prospect of massive interference in another nation's internal affairs... and, as J Wolfsberger says, of bringing brigades to the table, with all the political and financial costs that always involves.
