who will build the wall?

A few (rhetorical) questions.

Does Donald Trump expect U.S. Mexican men to build his wall?  It occurred to me today that many in the construction trades (at least here in the U.S. Southwest) are Mexican men who may not be interested in those jobs considering all that the wall represents.

Or, does Trump plan to employ his supporters to do the work? He has, after all, been promising them jobs. I wonder how they are at building big, beautiful walls? And working for the low wages paid to Mexican immigrants?
