>> The wall is estimated to cost $4m a mile (compared to Israel’s $1.6m), for a total tab of $8b for a 2000 mile structure.
I usually take any government cost estimate and multiply it by 3.5 to get the true number. So it would probably cost closer to $30b but hey, that is peanuts compared to what we spend on other things!
You can’t fence the Texas border so your only looking at around 900 miles.
