If 2.8 billion in profit is failure, then what does it take for capitalism to succeed? This should be enough empirical evidence that this system is completely unsustainable. How much money do you have to extract before it is "enough"?
I think you sum up rather well one of the main failure of capitalism here.
Capitalism is possible and sustainable only with a high growth.
High growth isn't sustainable in long periods of time.
Capitalism isn't sustainable in long period of times.
Quite easy to understand, a kid could understand that infinite growth isn't possible. But they try to make you believe it is thanks to services and financial market, even though any economist knows you must separate financial market and real life industry...
