@farmerman,
Legislation on tariffs is certainly an interesting field of study. We had a case about 20, maybe 30, years ago when it was discovered that the US government had a list of constituencies in Great Britain where certain famous products were manufactured. Harris tweed comes to mind but there were many others. Melton Mowbray pork pies.
These constituencies were threatened by targeted tariffs if proposed changes to steel tariffs were introduced.
But that is by the bye.
I had been under the impression that certain provisions in the Taft-Hartley Act had been applied by the courts more strenuously in regard to teachers in schools and universities than others on the grounds of the undesirability of permitting the dissemination of subversive doctrines from the teacher's dias and the professorial chair. A point I made years ago. Teachers being required to take loyalty oaths.
I suppose Senator McCarthy focussed so much on Hollywood precisely because of the educational aspect of films.
Some of these sorts of provisions have extended to people working for private firms engaged on government contracts which, as I'm sure you know, must be a very large number. It would probably be a stretch to envisage such firms as those supplying bagels to the PX being included but there are many other contracts of a more technological kind to which a similar justification as that applied to teachers, professors, writers, film-makers and media generally. The educative function of recorded music being notorious for its efficiency.
As you often remind me I know very little about these sorts of things so I thought you being an expert on the ground, in the thick of it so to speak, could supply me, and possibly others, with some guidance.
