The reason that tweet is wrong is because all studies show that White people produce more value per unit of time than anyone else. Sure, China can pay workers less, but those workers produce garbage. The issue is that Americans demand quantity over quality, so they place a premium on the Chinese garbage. But even in the realm of something like microprocessors, an American plant can compete economically, but there is a strong desire to make sure we don't, so that fewer Whites have good jobs.
