I seriously wish we could be money on it, because Trump has no intention of doing that. The fact he said, 'hew will Mexico pay for it,' was a tipoff he was making fun of people like you.
But worse still. the wall wouldn't make a difference. If Trump had any knowledge of conservative economics, he would understand that. As long as the U.S. is incentivizing illegal immigrants, they will get here.
Here is Donald Trump’s plan for how Mexico will pay for the wall:
Mexico must pay for the wall and, until they do, the United States will, among other things: impound all remittance payments derived from illegal wages; increase fees on all temporary visas issued to Mexican CEOs and diplomats (and if necessary cancel them); increase fees on all border crossing cards - of which we issue about 1 million to Mexican nationals each year (a major source of visa overstays); increase fees on all NAFTA worker visas from Mexico (another major source of overstays); and increase fees at ports of entry to the United States from Mexico [Tariffs and foreign aid cuts are also options]. We will not be taken advantage of anymore.
