To eradicate poverty global GDP would have to increase to 175 times its present size if we go with $5/day. In other words, if we want to eradicate poverty with our current model of economic development, we need to extract, produce, and consume 175 times more commodities than we presently do. This is horrifying to contemplate.
Yes, a horrifying contemplation. The idea that someone employed by the London School of Economics thinks that GDP measures commodity consumption.
Might I suggest just a little wander down the corridor to the people who know these things? Like GDP is a measure of value added, not physical commodities extracted, produced or consumed?
Christ, they managed to get it into my thick head as a student, they should be able to crowbar it into the mind of one of the staff.
