I think people are being short sighted. Asian economies are still growing at a good clip with still 100 s of millions of people aspiring to get ahead and over the next few decades will move into an ever growing middle class in Asia.
These people will demand better housing, transport, want to own cars, washing machines, the latest smart phones etc etc.
Europe is still in the doldrums but it will pick up eventually and the U.S. economy is starting to show strong signs of growth. many large multi national companies are in good shape (they've survived the GFC and have come out stronger) they are sitting on massive amounts of cash but have been resistant to reinvest over the last few years. Once they are confident in the recovery there could be a massive investment from these companies in plant and equipment, new staff etc etc
It would not surprise me if in a few years time we are in a massive boom time and demand for resources is bigger than ever
