the 80% tax on electronics since the 80s was because brazil had a few chip foundries.
two of them started cloning cpus designs (8080 and 68k iirc). they sold well all over the (1st and 2nd) world (still no local market). until one company did a publicity stunt lying they had a full mac clone (it was an actual mac, but they did have something else).
then apple and others pressured the US state department, which pressured the brazilian gov with tarifs on oranges (most of the new elite created in the millitary coups were now big land owners and orange was the cash crop). They were so afraid of the tarifs that they closed both factories as requested, and added the import tax as a good will gesture on top!
and many (30%) brazilians today think another military coup will sort things out
I was going to snidely ask what Argentina's excuse was for its import tax on electronics, but it's been a decade since I lived there, and it appears they dropped the tariff to zero at the start of this year (2026). Really, talk about holding your economy back for the wrong reasons: Making it wildly expensive for people to get the tools they need to bring money into the local economy. Besides, all it did was open a black market.
Forgive me, I'm unclear on one thing -- the import tax was added as a goodwill gesture? To whom? I mean, who was this done to placate? Not the US companies, and not the closed factories, right?
