Truth is there are no valid estimate on what a fence would cost only scare tactics like yours. Get a life.
On the remote possibility that your figures "are even close" keep in mind the right fence will end or severely stop 100-150 billion dollars per year costs of illegals.
Such as 6.7 billion per year to jail them,welfare costs,terror threats-- how do you calculate another 911? What that will cost the nation,social costs,medical costs ever been to a ER room where the illegals flourish? You don't have a clue dude.
“Ignorant turd” - now that’s a rejoinder! Perhaps you should take a look at yourself in the toilet water next time.
There are perfectly valid estimates to what any fence would cost - all one needs to know is the sort of fence to be constructed and the length across which it is to span, and most contractors can give you a tolerably good estimate.
Keep in mind that the “right” fence wouldn’t do a damned thing, certainly not anything you’ve pooped up.
A border fence would be nothing more than a pyhhric victory - talk about the liberals/democrats spending this country into penury. False conservatives and their religious fanaticism about “The Wall” will end up making those liberals look like the souls of fiscal prudence.
That’s all you are, a false conservative, with an overweening, xenophobic religious obsession with an inanimate object. The border fence is your golden calf, your false idol.
