Is it worth $20 billion to keep out 100 of them? 10? What is the magic number that justifies that expense? You don't invest billions of dollars in machinery unless you know exactly what efficiencies it will provide and how that will translate into profit for your company. Investment must achieve a worthy goal. You don't just spend money blind HOPING it will do something good. So why aren't we inundated with provable irrefutable statistics about how many millions of Mexican rapists/murderers the wall will keep in Mexico? Is it because they don't have a clue and are flying by the seat of their corpulent pants? Wanton promiscuous spending of taxpayer dollars for an UNSPECIFIED goal? Seriously? What kind of ignorant doofus does that?
