Civilized countries have maternity leave. Most are funded from the government's unemployment insurance funds. The only 'burden' on the emp;loyer is that the job is granteed upon the woman's return. Canada gives 12 months. EI payments are just abut minimum wage.
This is where you'll come up against the knee-jerk "doctrine" of American Exceptionalism which, if you examine it closely, translates as "If we didn't invent it (or at least believe we did), we won't utilize it, because we're not like anyone else, especially when it comes to emulating things that make other countries' citizens' lives so much less arduous because Amurika, **** yeah!"
It's entirely motivated by ignorance and emotionalism, and you can't make a dent in it. Best you can do is showcase it for the thinking American who will gradually distance him/herself from the Looney Tunes, as they're doing even as we speak.
