Why settle at only 40%? If quotas are allowed and Norway wants to be the perfect "egalitarian" society then everything should be divided 50-50 (or 51-49 or whatever the sex balance might be in the population). Heck, why stop at boardroom slots??? That's small potatoes compared to socialist control of every aspect of economic life.... Everyone should be required to fork over 100% of their earnings to the state for the nanny-state to distribute with perfect "equity" as it sees fit..... don't stop with mere grubby dollars and cents issues, Norway should require that everyone have sex just as often as physically possible, with everyone in sight on some perfectly random "equitable" basis, so that no one ever feels neglected or disadvantaged or slighted by the free choices made by individuals. That may seem like a far-fetched example, but it's not: the Euro-twit-socialists want to abolish free choice (except for women to murder their babies) and use the government to force everyone to live by socialist weenie dictates.
Actually Norway should make it the law that the male to female population should be in the ratio of 1 male to every 10 females...... Imagine having so many Scandanavian blondes to yourself!
