U.S. trade numbers for March came out today. A few striking points:
Exports rose to an all-time high.
Exports plunged during the recession, but they've been growing strongly for a couple years now, and are back above the pre-crash peak.
Growth is coming from a broad range of categories — everything from industrial machinery to corn to royalty payments. (When U.S. companies get royalty payments from overseas, it counts as part of exports.)
