Nobody flew to argentina they were just fired. There are interviews with the last employes reporting that they didn't even got pay after they were fired. It was a suprise decission for them too. What you are saying here is just no sense.
Actually using these values it should be closer to 60% as the states taxes is over the import tax and the federal tax. It should be like this: (15%*10%)/(1-17%). Yes taxation in Brazil is confusing.
As for the 40% remaining it should also have reservation for financing as it is common in Brazil to offer 12x flat rate financing on purchases even thought we have around 10% inflation annually and high default rate. But i agree that around 20% to 15% in this 40% gap should be additional profit over Brazilian operations.
We have multiple Ministers of Justice and multiple level courts on Brazil , so an higher court can block lower court decisions, even more when that is still been processed.
Is not only the import tarrif, we also pay federal tax around 10% and state tax around 17% and those are couting the import tarrif and the cost of shipping for it's base. I also want to add here that 90% of salary workers in Brazil receive less than R$3500 as salary each month, before income tax, so for buying even an iPhone 14 you need to save almost 3x your montly wage.
