-30 C is really incredibly cold. You just can't stand around in that without proper clothes.
I think the problem is that a lot of Americans are incredibly servile and will obey employers, authorities etc., even when it's harmful or dangerous. I especially remember a case where a woman was in court and was sexually assaulted by a marshal, right there with the judge ignoring it. But what I found very curious was how he was obeyed, and how the judge was obeyed.
Here in Sweden, neither judge nor marshal would have been obeyed.
I think the servility is probably caused by the experience that employers and authorities can get away with anything, and a fear that they will do worse if challenged or attacked.
