That's because the benefits are expensive, from a capitalistic point of view - six weeks maternity leave? That's six weeks of lost productivity!

I think it's important that everyone keeps defending the liberties and rights that we (in Europe) have right now - and that the people in the US that just accept their shitty working environments because it's considered normal fight it, and demand what I think is getting basic human rights like caring for your newborn without losing your job or getting into financial trouble over it.
