"taxes for the new generation"?
What evidence is there that extended ml helps the children anyway? It's farcmore about the mother's wants and "rights" than it is about the babies.
Fine if you want extended leave, work and save to pay for it, if not its a luxury you can't afford.
However, I wouldnt support it regardless of cost as I really do think, taken too far and being just for mothers (as opposed to shared parental leave) it would badly damage the career projects of girlswomen
