I know it is crazy. Here are some factors that I feel contribute to that 33 cent steak knife delivered to your local shop.
1 - over capacity in China where they are making jobs not steak knives
2 - China is not covering their long-term cost of capital
3 - state banks beholden to party bosses are making lending decisions based on the need to create jobs not allocate capital to where it will earn a decent return
4 - mines are also not covering their cost of capital and competition is keeping them from passing along all their costs
5 - mines are not recovering the costs of cleaning up their mines after they close, instead they declare bankruptcy and move on leaving the cost of clean-up to others (usually the government)
6 - even where governments know the mines are polluting they are fearful of losing jobs, especially in the developing world
7 - efficient supply chain management has cut much of the waste of transport from the system (a genuine benefit if you will).
8 - stores in Canada and elsewhere see demand stagnating and they are trying to cover their short-term, variable costs by offering low priced goods, even at the expense of long-term profitability
9 - yes, China does have a lot of underemployed labor so this keeps labor costs for the most part very low
10 - competition from other developing countries means that everyone is striving to be 'the low cost producer'
Just my own ideas in any case. Those 33 cent steak knives will likely start to turn black in a year and lose their edge the first time they hit the side of the plate, but they are cheap.

The organized state is a wonderful invention whereby everyone can live at someone else's expense.
