If you pay $2000 in taxes, yet get it all refunded back, the end result is you paid nothing.
That's the reality for nearly 40% of all "taxpayers".
In terms of profit, the illegals took jobs from americans, who then used welfare, entitlements. That's a loss.
Plus, I used your average rate, tax tables to find that if they are all single, at best they paid $3K.
Any children, wives that $3K drops like a rock.
In other words, they don't even break even, let alone show a profit.
And I didn't include the cost of education, or the illegals in jail. (At a much higher rate the citizens).
You have the economic sense of the underpants gnomes on southpark.
