First of all, when we think about quantity is when there is a forward movement, as a toward goal, or growth.
And then, speaking about quality, it is when there is a gradual betterment, or a progressive improuvment of society.
So we are going to see two documents. The first one is a cartoon by a cartoonist called Polyp which publishes his cartoons without any copyright on his webpage: http://www.polyp.org.uk/index.html
So we can see that the cartoon is divided in four images. There are rats that seem anxious or even stressed or scared. There is in the middle of the four cartoons some words like: "work harder" or "keep going".
In this cartoon, life is compared to a race for owning and consuming more than the others, and humans are compared to rats, because we all do the same and we just follow the society with worring about what we want, we just worry about quantity.
The second document we are going to study is a graph about life expentancy through the second half of the 20th century.
Thanks to this cartoon we learn that life expentancy has grown since 1960 to 2010. So that we can conclude that our life quality has improuved with consumer society.
As a conclusion, we can say that even if the quality of our standard of living has improuved, we seem to be too worried about what we own and we are always looking for having more quantity, instead of having less but still a life with quality.
