Even if immigrants take USA jobs, don't they consume proportionally to maintain supply-demand equilibrium? I heard many times politicians argue that immigration (in USA in particular, but applies to anywhere) are taking "real" Americans jobs. Then I tough, but they also are new consumers on the market, so they create supplies too. If immigrants also consume goods in a similar quantity and type as Americans, that will produce new more demand and thus the extra supply the jobs produce will be "justified", "balanced" or "matched". 

Obviously, this economical situation is EXTREMELY complex with millions of factors: how productive/educated both populations are, average age of immigration, in which sectors will immigrants work and if they will overload some part of the economy with too much supply... There are millions more factors.

The only thing I care is if my argument disproves the IMO fallacious argument 


  "Immigrants will take our jobs"


Tell me if this in more correct:


  "immigration will prompt the creation of more jobs and the new
  population demand will (hopefully, if everything goes well, which would
  not) balance with the new supply, without taking jobs in
  massive proportions, thought some people may loose jobs to more
  skilled immigrants."
The only argument that I think can be made is that immigrants often don't consume similarly to Americans. Large amounts of salaries are sent home from the US by immigrants which means that money is now out of circulation. 

Additionally, coming from poorer countries with a lower standard of living it can be argued that immigrants will choose to live a lower quality of life in the US which again could cause a decrease in Economic activity in the U.S. 

Lastly, for illegal immigrants wage/labor restrictions don't always apply to them meaning that U.S workers who are protected by these restrictions now have to compete with workers who do not have those restrictions which can drive down U.S employment and wages for workers across the board.

With that said, I think immigration as a general rule increases economic growth in the long run.
