It’s not entirely clear to me why tariffs would help your local logistics businesses? Doesn’t the same amount of stuff get moved around , just changes origin? I believe you I just would like to understand
Packaging is a support industry (other than stock boxes which are bulk manufacturerd for things like moving companies, etc).
So... the more companies making things or shipping things, the more boxes are needed. Financial and govt analysts use the packaging industry as kind of a canary for the general health of mnaufacturing and retail as it is on the end of the long tail for supply chains. Packaging is the first to decline and the last to pick up with the cycles of the economy.
