Earlier quoted context omitted.
"Living wage" means the ability to live, not scrape by with the bare minimum possible.
I feel like I’ve eat pretty well, and my household food costs are almost half what the calculator shows. Similar for vehicle costs etc. After looking at the method, I think the calculator probably has some bias towards “what society has convinced us we need”. To a certain extent that is a relative and subjective perception problem, and one exacerbated when you live in a society with a lot of consumer debt.
Behold, "averages" are not perfect.
