Trump all along has been told by Mexico and Mexico's politicians that they would not pay for the wall yet Trump persisted with his statement. For one it wouldn't be the first time a politician was wrong, remember everything Obama promised about the Healthcare bill? At least if the wall doesn't get paid for by Mexico it's not going to affect every American as drastically as Obama, and the Democrat's, Healthcare fiasco where monthly cost were at least doubled if not tripled and worse the out of pocket deductibles, money out of a families pocket before any insurance ever took hold, quadrupled to many thousands of dollars all so policies could pay for abortions and sex change operations and birth control.
So if the wall never gets built Trump will have done far less damage and harm than Obama and the Democrats did when they had their turn. Also there are plenty of ways in which Mexico gets money from the US that could be tapped to pay for a wall we have yet to see what's done though. That doesn't mean it won't get done but I'll take far lower unemployment, much better economy, booming stock market any day over the wall especially when immigration has dropped on it's own account of the Trump Government's stance on Immigration. A policy vastly different from Obama's come on in and stay policy which was no policy at all. At least Trump and Trump's justice department is prosecuting illegals and telling law enforcement to enforce the laws and inform ICE whereas the Obama administration and Obama's justice department told law enforcement not to enforce the laws.
Minorities will one day see the result of the Democrats catering to illegals over their own interest. Interesting that under Trump minority unemployment is at historic lows not seen since figures were recorded back in the 1970's. Yet Trump, the Republicans and their policies and economy are getting none of the credit. Why is that?
