Why haven't consumer goods taken the same price drop as gasoline?

9. Lower oil prices, at present levels of production cost, are not economically beneficial

With oil below $30 a barrel, the majority of US and Canadian oil production (which comes from tar sands and oil shale) is not economical to produce, but the investment in production infrastructure is also a sunk cost, so there's no reason to not keep producing it (even though the break-even is somewhere in the range of $65-75 a barrel). So at current oil prices, US-produced shale oil is losing $35-45 a barrel, which is a loss of $2 billion a day to the US economy. And that doesn't take into account the thousands of job losses in Texas and North Dakota and elsewhere due to the collapse of the oil price, nor the large amounts of debt taken on by oil drillers that's not being serviced because they're not making enough money to do it.

Further, the economy is global; China is experiencing something of an economic crisis, with productivity and growth down very considerably (the Baltic Dry Index of shipping, which is a useful measure of international trade, has recently been at all-time lows).

And the cost of consumer goods hasn't fallen because the inflation rate is still (barely) positive, at 0.7%; a fall in the price of consumer goods would be the result of deflationary pressure (which may arrive, but hasn't, yet).
