Basically the price of Pork in China is a major issue. If it goes to high, you risk upset people. And if you use Colistin, a super antibiotics, with your pigs, it increases their weight. The problem is Colistin was one of the last antibiotics that worked against super bugs.
And why are not more antibiotics being developed? Cost in the US. The average drug costs is $2.6 Billion to get approved. And it does not make financial sense for antibiotics.
Great article that is worth a read. It's amazing how technology has doomed the video rental store. When I was speaking with a handyman, and he had Netflix, I was amazed. My family was a later adopter of Netflix.
What I have noticed is textbooks get a lot of junk added to it, multi media, web downloads, etc. that are never used. The editions go through minor changes to reduce the resale and renting market every year or two.
The Chinese Textbooks I sell the most are $29.95, but they are more focused on the K-12 market.
What is happening due to the super high price of Textbooks is a rise in:
Use of online textbooks
Increase in used textbooks
It's so easy to sell a used textbook now. A major publisher, Cengage, was in bankruptcy. Print book sales have been decreasing. Interesting, they estimate by 2018 that 40% of it's revenue will come from digital. My 2 cents - still clueless. The key word is value, not a compelling solution. And the huge increase in textbook cost has increased the attractiveness of textbook rentals.
Sad. It's hard to be a teacher in some schools / districts. I was a substitute teacher and I took whatever job was available, often at the worst schools in the districts I subbed at. It was a learning experience - which is why I made sure my daughter went to a different district...
