This thread is so frustrating.
The speech is not meant to be about what boys/men should do. It is about the ambitions and expectations of girls. Insisting that boys should be included just means that girls, yet again, get relegated to the background.
Boys do not face the same dilemmas because of the culture of our country. They are allowed to have a 1950s 'traditional' role, or they are allowed to be 'new man'. Either way is fine and draws no debate.
For girls to thrive in the corporate world, they have more problems. They almost have to behave like 1950s men, which means being totally committed and competitive. They can do this in the early years of their career, without question. However, it is hard for women when they start having children. Priorities change, compromises are made. When they used to say 'how high' when their bosses asked them to jump, they are now accountable to the childminder and her ticking clock. Yes, their husbands should do their fair share, and most try their best, but men and women are wired differently.
My husband is great with the children and the house but he doesn't worry about the same things I worry about. If he needed to pick up children from a childminder, and his boss called him in five minutes before he was about to leave, he would have the meeting. It would not occur to him that he was now on £5 for every 15 minutes, nor would he tell his boss it was inconvenient. He wouldn't worry about the future relationship with the childminder. A woman does get stressed out by these things.
I have been in that environment. I worked for a multinational while having my first two children. Juggling travel was a constant stress for me, and trying to not bring attention to my problems. I used to delegate most travel to one of my direct reports, hoping that my boss wouldn't notice too much and command me to go wherever.
I worked through this because I thought I had to. I was privately educated at great sacrifice, and the first person in my family to go to university, blah blah blah. I felt that it was my duty to have a 'career'. I couldn't give up so retrained and downshifted to a more family friendly job. I was finally rescued from this by having my third child (childcare too expensive to justify working). What an epiphany.
I spent several years as a SAHM (loved it) and resumed my career quite smoothly, 10 years behind where I might have been but very happy with my lot in life.
I can look back and see that I had a couple of years of working in a high powered environment that didn't make me happy or fulfilled and generally caused me stress. If I had managed the situation differently, I could have had a very workable compromise, which would have still ticked all the boxes.
That is the advice to the current crop of bright girls. Manage your career to suit your values.
