This is the kind of big government republicanism that is killing the party. Import tariffs benefit to benefit a few rich corporations and key donors, and screw everyone else. Frame it as a return to the "good old days" that never existed like you remembered. Taft-Hartley existed in those days, and it was a terrible time.
Boohoo, thay might have half their markup eaten up if they built them someplace that doesn't have to have suicide nets underneath the windows of the factory.
And if you complain about the stupidness of regulations, the responsibility shysters barricading proclaim you hysteric or careless. My personal favorite is lumber-work, where in some of the heavy duty protection equipment you are supposed to wear is so heavy, people make exhausted stupid mistakes and get injured because of the security measure. Example references the Kevlar jackets and trousers- lately partially replaced by lighter plastic protection gear. The worst part is - some regulations introduce routine- and routine kills.
