Why 2 standard deviations bars would make it comparable?
P.S. I am a proponent of the idea that education's value is overinflated, but I believe this graph is improper way to prove it (at least, clearly insufficient). A better proof would be based on comparison between those who learn and those who didn't, taking people with similar birthdate.
The point of the plot is not that the value of education is inflated. The point is that "socialised education" ever since the decade in which the American Federation of Teachers grew by an order of magnitude in membership and started getting overly political and merging with AFL and such has been a pretty bad deal for taxpayers and their children.
This point sounds reasonable. This is not just education. Justice, politics, culture is becoming more "socialized" too. Instead of "my house my castle" you'll hear more of "we're community", "protect the environment", etc. Not sure where it's going, but it's hard not to notice it.
