This movie helps progressive people address one of the main criticisms of the right and capitalists: what would you do differently if capitalism and globalization is so bad?
Argentina was a country where public utilities had been sold off and money fled the country. Factories were left empty, owing millions of dollars in taxes to various levels of government. The workers thought: we don't have jobs, so we can't buy things for our families. There are no jobs, because people aren't buying things for their families. So they broke the cycle, and with government approval (eventually) occupied the factories and just started producing items for themselves and their neighbors. The co-operative/collectivist movement in Argentina flourished.
The movie shows it was far from easy, and there are many hurdles left to overcome for this country and its people. But it's a hopeful message that if you buy locally, use locally produced services and products produced "locally", you create a viable economic cycle that enriches everybody. You may not have $40 microwaves produced someplace else on the other side of the world, but instead you get a quality product produced by your neighbour, that doesn't require the expense and waste of trans-global shipment. Then, the makers of cheap microwaves will be forced to pay their workers more in order to create a local/national market for their products, rather than using slave labour and shipping the products overseas to the "first world".
Okay, I'm off my soap box. Well done movie with real emotion and appeal.
