"Economic refugee"? This is some way to make a word lose its meaning. At this point any immigrant would become a refugee.

"A refugee is a person who is outside their home country because they have suffered (or feared) persecution on account of race, religion, nationality, or political opinion; because they are a member of a persecuted social category of persons; or because they are fleeing a war." https://en.wikipedia.org/wiki/Refugee

Sigh: According to the researchers, a lack of protection of migrants in the region was based on a "false distinction" between a forced and an economic migrant, instead of focusing on the real and urgent needs some of these migrants have. The report suggested that a better term would be "forced humanitarian migrants", who moved for the purpose of their and their dependents' basic survival. https://en.wikipedia.org/wiki/Refugee#Economic_migrants
