To your second point, customers often do try to fool vendors into thinking they are in the consumer group that is offered lower prices. As an example, non-students use their old student IDs all the time.
Re: correlation with a legally protected class, this can be solved with marketing. Price discrimination based directly on gender would be illegal. But if you put one product in a blue box in the "men's" section and one in a pink box in the "women's" section, consumers will self-select. This is very common with razors, soap, and other such products.
Lastly regarding your edit, if a consumer pays his or her reservation price they are left with zero surplus. But that doesn't mean the transaction was pointless. The consumer gets the consumption value of the product. I'm willing to pay at most $2 for a bottle of Coke. That's my reservation price. If I'm offered a Coke for $2, and no vendor offering a lower price is available, I will pay that price and enjoy the Coke.
That is an impressive syllogism you've got there.
This is simply untrue.
Also, if a VR system can perform well as a hiking simulator it would be able to realistically simulate things that don't exist, places that are too difficult/expensive for an average person to visit, or experiences that are too dangerous to attempt in reality.
EDIT: For example, I'd love to visit the moon or Mars but it's highly unlikely I'll ever be able to physically go there. A highly immersive VR simulation would be very appealing to me!
It seems to me we're much closer to a great AR experience than truly great and immersive VR.
His table of particularly overpriced journals in economics is dominated by Elsevier journals: http://www.econ.ucsb.edu/~tedb/Journals/roguejournals02.html
Hopefully we see more academics collectively abandoning such journals like Knuth and the Journal of Algorithms board and these other examples from Ted's website: http://www.econ.ucsb.edu/%7Etedb/Journals/alternatives.html
Until replicability is required by top journals, and replications are appropriately valued by these fields, you'll continue to see this kind of drek trotted out.
Publish or perish.
I imagine it is much easier to homeschool now that PCs and the internet are ubiquitous. My mom had to do a lot of work assembling curricula and sifting through textbooks that would be much easier today.
Homeschooling works better in groups. It ends up being like a regular school environment but with much smaller class sizes and heavier investment by the teachers. In my teens, my group met on Saturdays for a long intense literature class, Mondays for most other classes, and individually for math. Naturally we had lots of reading and homework to do the rest of the week. Some of the "classes" I took were more in-depth than my university courses.
Homeschooling taught me my most valuable skill: how to teach myself. I taught myself algebra because I didn't like the way it was explained to me (textbooks offered more rigor). I read lots of classic literature in my spare time, taught myself how to touch type, play guitar, etc.
The biggest downside was not having a guidance counselor. No one in my family had been to college, and that led to me making dumb mistakes in the college application process (like not applying to top schools because they were too expensive, not knowing they offered substantial need-based financial aid). I also struggled to learn to program on my own.
I would argue this is when most economists lost influence in Washington, while a few like Art Laffer gained massive influence. The New Deal era prior to this was largely motivated by the work of noted economist John Maynard Keynes. Although the causality is debated, the New Deal was followed by recovery and economic growth. Economists gained influence in the public sphere because of the effectiveness, real or imagined, or "Keynesian" economic policy. These folks had lost sway in Washington by the early 70s due to the stagflation crisis[1] and the collapse of the "New Deal coalition" after the tumultuous 1968 presidential election.
The late 1970s was dominated by the ideas of economists like Art Laffer, who took an uncontroversial economic idea "tax revenue is maximized at some point between 0% and 100%" and turned it into "the tax revenue maximizing rate must be lower than our current rate" without presenting sufficient evidence for his claim. This was a convenient for some in Washington who already believed this to be true, and thus the "Laffer curve" was born. The following era of deregulation and lower taxes on the wealthy likely played a large role in increasing income inequality.
[1] The causes of stagflation are still debated, but I am convinced this was directly caused by the OPEC oil cartel using it's market power to quickly inflate the price of oil by 400%, creating a massive supply shock that started the stagflation spiral.
