the wall is there!

This wall nonsense is such bullshit. It's just a way to fire up his racist base. We already HAVE a wall on the border everywhere it's makes sense to have it. Some of that border is so remote putting up a wall is insane and would be ridiculously expensive. Look up some of the terrain between Texas and Mexico. Natural obstacles, indeed. 

"Build the wall!" (what happened to Mexico paying for it?) Now the US is supposed to pay for it? 

It's such a red herring. Yeah, it's all them Mexicans (that pick your vegetables, do your lawn, etc, etc., and take jobs that Americans just will NOT do). 

Hey, why don't we have a wall all along the US Canada border? In some places, you can just walk over and easily meet up with anyone in a car. Canadians may be white, like Trump, but Canadians themselves are not trying to sneak across. 

Donald Trump's Mexico wall: Who is going to pay for it?

President Donald Trump has set in motion his plan to build an "impenetrable, physical, tall, powerful, beautiful, southern border wall" between the US and Mexico.

The border is about 1,900 miles (3,100 km) long and traverses all sorts of terrain.

Mr Trump says his wall will cover 1,000 miles and natural obstacles will take care of the rest.

Trump himself says natural obstacles will take care of "the rest". So not every single mile will have a wall.

The 650 miles of fencing already put up has cost the government more than $7bn, and none of it could be described, even charitably, as impenetrable, physical, tall, powerful or beautiful.

Adding even more to the expense, the new 1,000 miles would crisscross private land, which would have to be purchased, perhaps by legal force, or financial settlements made with owners.
