Financial cost is simply a proxy for supply and demand of finite resources (broadly, obviously there are various distortions that come into this) and as population continues to increase and expectations of living standards rise, resources become ‘increasingly finite.’

On reflection I totally agree, that money is a proxy for something else, one of those things being environmental cost, which currently is externalised by the west, and the cost born by poorer less powerful people, eg those in Sub Saharan africa. I wonder how much health care $2.5 never mind $2.5 million, will buy in Sub Saharan Africa?
