We have over 500 000 illegal immigrants living in Arizona. And we simply cannot sustain it. It costs us a tremendous amount of money of course in health care in education and then on top of it all in incarceration. And the federal government doesn't reimburse us on any of these things.
I like mathematics because it is not human and has nothing particular to do with this planet or with the whole accidental universe - because like Spinoza's God it won't love us in return.
