If you read the history about the Chinese American experience, many of the protests and riots against the Chinese were basically about envy about their success from working too hard with hardly any days off during the year and doing jobs no red-blooded american would take.
In many places around the world there are laws on the books that prevent retail stores from opening at certain days or times so that the local mom-and-pop stores can have a day off and not suffer any competition/losses when the other stores (ie, chain stores, department stores, malls, insane

immigrants-owned stores) are open.
