Trump rightly said that Mexico has abused the U.S. as a dumping ground for the poor and discontented in Mexico. After former Mexican president Vicente Fox insulted Trump in a profanity-laden tweet, Wolf Blitzer asked Trump for his response.

Trump said "the wall just got 10 feet taller."

I love the unyielding resolve, and defiance. This is one area where I feel Trump has not laid out the case enough for the enormous cost Mexico has shunted onto the U.S., that would explain why Mexico should be required to pay for the wall.

He could make them pay for the wall with just a 1% or 2% tax on wire transfers of cash by Mexicans to relatives in Mexico. (as I've detailed before, wire transfers of cash by Mexican immigrants to relatives in Mexico is the 2nd largest source of revenue in Mexico. The largest is the Mexican oil industry. Trump could bring Mexico to its knees just by indefinitely suspending cash wire transfers. )
