There is an old saying about judging the character of a person by how they treat their help. Have some fun at the expense of the Germans. Go see this Daily Mail book review of a tell-all by a Polish gal who went to Germany to work as a cleaning lady.
She says Germans weren't all that nice to work for. On the other hand, Poles have lots of historical reason not to love the Germans.
Her experiences sound like a watered-down version of how oil-rich Arabs treat the Bangladeshis and Malaysians who work for them. At least she wasn't tortured, raped or killed.
