I'll be honest, I never liked this argument. First, it didn't happen then, specially if wages being halved meaning that there isn't even a theoretical possibility of working half the hours for the same pay. And why does doubling labour force halve wages? Land is limited so the higher competition can mean more workers mean higher prices, sure. But for everything else, productivity of workers per hour increased. This isn't the middle ages where demand for labour is more or less limited by the availability of agricultural land. Why can't the new and old workers capture the same share of the pie they produce as before women joined the wage labour force?
