BG believe it or not some people are at the limit. They live as simple as they can. They dont have lawns to water, they already are on the oatmeal and yogurt diet, and they are already on or near the threshold.
They will not cope. Your idea for increased sustenance is great. Wake me up when it becomes a reality. Meanwhile monthly bills keep coming in for these people.
There are plenty who can cope. There are plenty who cannot. Telling those who cannot that they can simplify when they already have their backs against the wall is elitist and ignorant.
