Like Trump, you are conflating a border wall with border security. A ten to twenty foot steel slated structure can be climbed when no border security is present. When improved drone and camera tech is available, it is a more cost-effective way to monitor illegal crossings along with repairing present infrastructure. Couple that with hiring and training additional border patrol and you add to the economy and get people working.

When undeniable an unarguable fact tells us that most of the elicit drugs come from port of entries and legal entry points, along with those already produced by cartels in this country, a wall will do zero but allay your fears and fulfill Trumps bloated ego.
