I'm serious about the MOOC, especially for someone with your interest in the subject. I think you'll find it really worthwhile, even if you took the courses in undergrad. I did my MBA late and my life experience made those courses way more valuable for me even though I was essentially redoing them from undergrad.
It's always easy to find counterexamples to the current low inflation, but even many of those don't hold up to actual scrutiny. Take tuition for example, since we're talking about education and you used it as an example. MOOCs didn't really exist in 2008, now you can take almost any course imaginable from the best professors at the best universities for free! And even if you are a traditional student, tuition is a misleading number. I'll talk about Stanford because I happen to be familiar with it; tuition for undergrads is officially $44,000 and room and board another $13,000. However if your family makes less than $100,000, which is far higher than the nation's median income, you pay no tuition. If they make less than $60,000, still above the national median income, you pay no tuition or room and board. A simplistic calculation of $57,000/year to go to Stanford times X students costs $XXXXX is simply wrong, in fact very very wrong.
We can debate every item you listed and I could provide dozens of counterexamples, but I will leave you with one macro item that you just can't ignore. Since 2008 the price of energy has fallen by 70%. The price of metals is down 40%. These prices get baked into the cost of almost everything we consume, so either the midstream producers are all colluding and making incredible windfall profits without any of us realizing it, or prices in general have gone down or certainly haven't gone up. Keep in mind this is just an intuitive way to look at it in keeping with the intuitive feel of the thread so far. However in the end I'm going to go with the rigorous quantitative measurement of prices that makes up the dozens of price indexes produced by dozens of completely independent public and private entities around the world, absent some specific reasons why every one of them is inaccurate in the same direction.
Eventually it's going to end, and it won't be pretty.
