> It's not designed to be "equal". It never was. It's (nominally) for importing highly skilled workforce, which, naturally, would be earning somewhere in the upper quantiles, their ESL English notwithstanding. Instead it's mostly used to depress entry level wages for recent grads as well as to reduce overall cost of labor by dramatically boosting supply.
I'll grant you that immigration depresses the wages of the field they get in to: but thats true of any importation. Immigration restrictions are like tariffs, just on people instead of goods. Importing iphones from china also depresses wages of those who would manufacture them in the US.
Its the wrong way to look at it, its really not economics. If an immigrant produces X and gets paid X - Y, the country gets richer, period. And if the X-Y is used within the united states it becomes a virtuous cycle: if instead the immigrant works from outside and exports into the us, americans lose on demand and the American governments gift taxes to other governments.
If there are good reasons for immigration, they are not going to be economic, and this is so widely accepted in economics that its truly absurd to argue otherwise.
> Why? Seems like fresh grads could use...
Whatever conceptualization you make about the economic effect of immigration will have to be backed by the limitations of imports which have the exact same effect. Unemployment is not caused by immigration at all, it's even the other way around: any immigrant spends in the US creating demand for other jobs.
