This chart is supposed to show a decrease in the seemingly limitless pool of Chinese labor. I noticed it because it doesn't look like any of them majored in sociology.
For reference I just imaged searched "sociology majors" and came up with this for comparison;
The question I ask all of ye out there, who is contributing more to GDP?
Post script- Langman made an astute observation and I thought it warranted mentioning;
Sadly, Langman, you have to realize that to the sociology majors of the world, it's not REALLY about helping out the poor people, as much as it is doing the least amount of work to make THEMSELVES feel better. Ergo, it doesn't matter if the place is still a dump 7 years later, all that matters (in their mind) is that they tried. And warm fuzzies for everybody muffle the fact they've achieved effectively nothing.
It is the most hypocritical, shallow exception I take with the "charity pimps" of the world. It's not really about the cause, it's all about them. The poor starving people of country "x" are merely a means to make rich, spoiled preppy Americans who are too lazy to study math feel good about themselves.
