I think it's more about seriously studying the given case(s) without too powerful generalisation / creating stereotypes. Generalisation understood in this way is bad, mmm'kay?
That's the part of SilverTurtle's post that triggered my reaction. I don't think statements like "US car companies are good to their employees and freedom, in other countries the car companies are bad and run sweatshops" can be even considered remotely true.
