Ethnic competition thesis

The ethnic competition thesis, also known as ethnic competition theory or ethnic competition hypothesis, is an academic theory that posits that individuals support far-right political parties because they wish to reduce competition from immigrants over scarce resources such as jobs, housing, mating opportunities and welfare benefits. According to the theory, support for the far right should be higher in areas if there are more immigrants and more lower-educated and lower-skilled voters who would face competition from them (because of the relative ease of onboarding in low-skilled jobs, even for a non-integrated foreigner).
