Illegal immigrants are not arriving with MBAs in Finance.
They are taking the American citizen's housing welfare, social security, medicaid, hospital beds, school lunches, food banks, overburdening social programs, and yes - this is a big one, are you ready for it...the eggs.
Supply and demand.
High supply, low demand = low price
Low supply, high demand = high price
Your MBA in Finance should have taught you that in the first semester.
