It's not, people just love shitting on America. 14 weeks + 1 additional for each year served at US salaries + unemployment + paid health insurance for 12 months is extremely generous compared to the peanuts that Europe pays engineers.
Twisting words a bit: most of Europe doesn't get much worse severance than top US corporation. That's impressive.
IT in Europe also gets better severance etc.
Also, not checked in other countries, but in Poland for example: regular salaried employees get 3 month notice if tenure is 3+ years.
