Men write, direct, and play the lead in most movies. They write the news, journal articles, books, speeches, and laws. Then, they're more likely to hold those speeches, break those laws, and peer-review those journal articles.

They hold more power deciding which job gets paid how much, which group of people gets a parade on July 4th (soldiers, not nurses), and which profession to glorify in the next credit card commercial.

So, yes: our impression of a job's prestige is formed by culture, and that culture certainly was–and largely still is–dominated by men. And yes, of course that culture has the same impact on mens' and women's views. They are people, you know?
