Cost of living is cheap in China, so its not always sweat shops. Just that one day it will move to another country as the Chinese start to want more luxury in life. A $70 ARF probably cost only $40 when its lands in the US. Your ESCs that cost like $150 at United Hobbies cost only about $70 from the factory. Some nice EP ARFs that cost like $180 actually only cost about $70 landed in the US. They do make that much profit. Shipping is cheap, capitalism is a reality!
