From the point of workers in the destination countries, any influx of foreign workers replacing local ones and put pressure on salaries to be seen as bad is 100% understandable.
And if you look at the real, measurable data, most "normal" systems offer at least equal or even better specs.
HiFi is 110% hype. What they define as "smoother" or "more natural" sound is actually a quality loss.
It's often based on "that's how they sounded when I was young and heard my first record, and not as harsh and crude like they sound on a modern amp". All while forgetting that their sound setup back then was cheap, crappy, and made a massacre of the sound waves on any point between record and speaker.
So the deal violated (admittedly questionable, but still valid) US laws? Make the companies pay dearly for this, so they'll think not only twice, but a dozen times if ever asked again.
The Evangelicals in the US are a rather crazy, radical bunch in comparison to Roman Catholics here in Europe. And while Catholics here are more conservative than Protestants here, they are rather civilized. In many European countries the members of the Catholic are more liberal than the leadership in Rome, and there is a lot of stress between the common people and the leadership, mainly to open up as much as the Protestants already have.
Why at lower pay? I'd ask for more. The original employees already know the job, hiring and training someone new would cost way more.
