The transport (by plane) of fresh orange juice on a daily basis seems to me a unsustainable luxury.

Labour costs only seem expensive with cheap energy and plenty existing resources (metal, land, water).

I would imagine that having 3.5 billion cars (1 for every 2 people) as you have in some Western countries is impossible simply due to resource constraints. Not labour.

The cost of the natural resources required to make a product is dwarfed by the labor costs.  

boy is that ever reversing fast...
