Tell me, if you have a finite number of resources, power, water, fuel, supplies, food, housing etc, it's perfect ok for tens of millions to enter the country illegally and consume all these resources?
It’s never okay for anyone to come in here illegally.
But it’s not because they consume water and gas, which they do pay for. It’s things like free access to healthcare (via emergency rooms) which they don’t pay for, free access to schools (which they don’t pay for), and other public services etc.
