I look at recent popular movies and I see Little Women and Birds of Prey starring younger women, then a whole bunch of Bad Boys Forever, Call of the Wild, Dolittle, 1917, basically the same old, same old. If younger actresses are getting more starring roles, then good for them. Seems like a good thing to me. I've known a lot of actors and actresses and none of them think like this. Their dedication of their craft is a lifetime commitment--because some actresses have babies doesn't mean they are ready to settle down and be full time mothers once the kid arrives. Most never make anything like big bucks; most never find enough work to go around, which is true for actors, as well. You make it sound like acting is some sort of hardship for men. The actors I've known, male and female, actually love to act and most want to do it for as long as they can. So I don't see how the choice that you proffer here fits any known reality that I am aware of.
