It'll make the commute from Guadalajara to Montreal that much quicker!
In all seriousness, though... throughout history the turning point giving way to the downfall in any economy has been shifting from a production-based economy (that is, people that build stuff... like we kinda used to do) to that of any type of economy that just moves things around (trade-based, bank-based, etc)...
And now we're moving to benefit even less from our trade-based operations by exporting port jobs, and trucking jobs to a more significant extent.
Doesn't bode well for the long term, imho.
