Chinese business owners that don't believe in playing by the rules by illegally importing sub-standard products that give us Americans a nightmare buying experience when the product breaks before ever being used or catches on fire while in use or simply falls apart during use. Chinese business owners screw over their employees by underpaying them like slaves and don't feel its necessary to pay them on time because it's not important to them because they have millions in the bank. Chinese business owners that strap dildos to their heads and walk around screwing their employees over time and time again.
