Lemme be a regular monkey in the wrench here.
It ain't the value of the dollar that's important. Its the value of the workers. Remember when there was a feeling (valid or not) that employees were an integral part of a business and there was a mutual feeling of responsibility? Guess what. If your vision is good, you can see that in the rear view mirror now... as long as the road is straight and level. "Business is business" is the new battle cry, damned the employees and full speed ahead. If we have to, we'll just cut a few. We're here to make money, after all, and we can't do that if we have to be fair. Got to buy the wife that Escalade, ya know.
Your statistics are a distinction without a difference. High school, college, work experience... all irrelevant today. What prevails today is baseline reductionism. The bottom line and only relevant question is: "Can you live on it?" For more and more of us, the true answer is "no".
This is much less about the value of the dollar than being able to get by. Gasoline, adjusted for inflation, is less expensive than it was 30 or 35 years ago. Internet access? It didn't exist then. Health insurance? Hold onto your hat. Food? My guess would be that it about equals out. Housing? Higher. And even if the 'value' of a dollar has stayed level, wages have not.
I had a boss who used to justify herself by saying, "Hey, I have to buy the same loaf of bread that you do...". My response, the one and only time she said it to me was, "Yeah, but you can buy a lot more of 'em than I can".
Don't get me wrong; I have no problem with a boss making more money than a grunt. Heavy lay the head that wears the crown, and all that, ya know? But this "Just borrow $40K from your parents and start your own business" crap just doesn't wash. For one thing, if everyone started their own business, who would you get to work for you? For another, who would you sell stuff to? For another, can I borrow $40K? <grin>
Besides, I can't be my own boss. I promised myself long ago that I'd never work for another A-hole. <chuckling>
Today, it's getting a job, keeping a job and hoping you don't lose a job. It used to be getting a better job, learning your 'craft', working your way up the ladder, proving your worth, having it acknowledged. Anybody got one a them these days?
Sorry but I think we are comparing apples and moon rockets - Not sure if the data are accurate but
"In 1911 only about 20% of youth attended high school—and fewer than 10% graduated. Whereas, in 2010, about 90% of all students in Pennsylvania graduated from high school;" - so who was spending money sending their children to college in 1913? Not the rank and file that's for sure.

I am not an economist but I think the value of a dollar can really only be measured by looking at a good (say a bottle of whisky or a bag of flour, a can of tomatoes or a pound of carrots) and calculating how many hours you would need to work to buy that same good in 1913 and how many hours you need to work today to buy the same good. If you need to work more hours today then the value of the dollar has fallen. If you need to work fewer hours today for the same good then the value of the dollar has risen. All talk of luxuries and necessities and the value of a college education today does not really grapple with the question about whether the dollar has been devalued by the Fed and its role in the economy as the central bank and bank of last resort
