The freegans, most of whom are educated and capable of contributing to the economy, aren’t sharing the surplus wealth of the West with those who are destitute by circumstance rather than choice. They are competing with them for it.
The freegans’ Edenic myth is seductive, but there is no way to put the technological genie back in the bottle, or the demographic one either. Six billion people, however much we may deplore their impact on the environment, cannot sustain themselves by foraging for nuts and tubers. The way out isn’t backward, but forward, by using our wisdom, and even our much criticized technology, to forge a better and more humane society.
