$24 billion to Mexico alone
Mexico achieved literacy in their country some decades ago and WIDELY continues to distribute pamphlets on just HOW to cross over the Line, how to get work (temporary and permanent) and from whom to get it.
Mind you, most of that money probably ends up in the hands of the notorious coyotes but the "flow" north is unstoppable.
NO USE trying to convince the country of "equitable" distribution. APPARENTLY that word doesn't exist in Spanish when relating to money and work.
