“Stop building the wall on our southern border!” warns Elon Musk. “You’re building the wrong wall!”
Musk, the world’s foremost efficiency advocate, sees huge waste in building a wall to stop a few million migrants when there are potentially BILLIONS of space aliens who might migrate to earth in search of a better life. “The right solution,” says Musk, “is to build a Great Wall not at the border, but around our entire planet.”
SpaceX has already drawn up the plans. The space wall will essentially be a giant electrified hair-net around earth that functions like a cheap bug zapper.

“This would provide effective protection against a single ship or a migrating armada,” Musk said.
While the space wall will certainly be an expensive endeavor, Musk believes it can be made more affordable by employing native earth migrants willing to work cheap.
