I know some immigration experts like PhD guys. And they just laugh at America. As one of them put it "America doesn't have an immigration PROBLEM, it has an immigration SOLUTION. They just don't know it."
I have to agree. Too bad there's racism and all that.
Yes they are building the wall

Not only will it solve immigration:
- it will also solve the problem of bags of drugs being catapulted to the other side
- it will create at least thousands of jobs
- it will create new businesses and entrepreneurship like wall sightseeing
- it will be bigger and better than the wall they have in China
- it can be seen from space so SPACE FORCE pilots can pinpoint the exact location of the greatest country on earth at all times
- It will solve the problem of socialism because even if people elect socialism there's no money left to fund it
