A lot of people already did that and it's already cheap anywhere in the world. The thing is, to be able to sell it in the US you would have to be approved by the FDA and that's why Shkreli got away with it, there can't be any legal competition before at least a few years.
How is it amazing? Nobody ever said producing medicine is expensive, being able to sell it is.
This is at best a puff piece attempting to defame Shkreli instead of pointing the blame where it belongs.

Manufacturing pharmaceuticals is not cheap or easy. Even the US's National Institute for Health had to shut down producing drugs for clinical trials recently due to GMP violations.
