It’s mostly a combination of 3 things:
- Tons of infrastructure. If you decide to start manufacturing some random thing you can easily get all the stuff you need to get started.

- A huge population. That’s the main source of ultra cheap labor. Farmers in rural China can still make as little as $1.90 per day. All a factory owner needs to offer is more than that and they’ll have a line of applicants.
