Absolutely no idea what you’re talking about. I guess it depends on the country. Here, a lot of students pirate their books anyway. Personally, I didn’t buy a single book during my bachelors/masters.
I am glad this practice apparently isn’t universal. Basically the idea is that because pirating books is possible and they don’t get paid again for used books, the publishers have created DRM through the use of web portals that are required to turn in assignments and in some cases even tests. Access to these is provided with a new copy of their books in the school book store, or for the same/more price as the book sold separately. Without the portal, you cannot pass the class because they lobbied the school to make it illegal for teachers to accept your work any other way. The school gets a kickback from the publisher and they both make tons of money
Being pro-tariff can (and should) be like being pro-modern medicine. Targeted use saves lives, but the only difference between medicine and poison is the dosage and treatment vector. Tariffs should be used like every other regulation on the economy, but since Reagan the dosages of every regulation have all been way out of whack either way too low or way too high. There is a place for some protectionism, just not like this obviously.
