Yes, but it's better for the state to pay it so that because if companies pay maternity leaves completely, the cost is not distributed evenly.

I disagree, that should be the responsibility of the state and individual families.

It's a cost that is easy to foresee if your company is large. If the company consists of 1-2 employees, the company can go bankrupt from the costs. I've talked to an entrepreneur whose company actually did go bankrupt from maternity leave costs.
edit - I am not against the state picking up the tab, by the way. I just think it is one of those costs that could be paid either way and I have limited sympathy for employers who complain that they couldn't possibly be expected to plan for the eventuality that some of their employees might become parents.
