Without being a psychic I'll now magically read the minds of Scandinavian policy makers....they're right now all thinking...."I better not do anything that can in the slightest way be interpreted as discrimination of women or imigrants, or my job is fucked".
Our laws aren't discriminatory against women in the least. For the reason I stated just above. Scandinavian feminists are extremly active, powerful and quick to judge. Whether that is in every way a good or bad thing I'm not so sure, but it's aparently needed. We all know that under law, being a woman can really suck ass in the world. The system USA has with giving tax benefits to married couples...ie gearing the system toward making it easier for women to be house-wives, could never survive in Scandinavia. Our feminists would pick it apart and make a short job of the polititians suporting it.
Why the Scandinavian countries in spite of this have inequalies between the sexes is a seperate debate all together....and a lot more complicated one.
