I disagree. The peso today is down roughly 10% against the dollar.
That increase in dollar to peso purchasing power will cut that 20% border
tax effectively in half. The peso could very well drop even more, further offsetting any border taxes.
A stronger dollar/weaker peso will incent our muchachos from south of the border to get here and work for American $ however.
A 10% decline in the peso vs. the dollar cuts a 20% tax effectively to 18%. Which is not “half.”
