> They want the dynamism of being able to change jobs and careers, they all want the opportunity for career progression which for the most part isn't there (it's always been competitive).
Why do people want this though? 50 years ago, you could be a mechanic, work 50 hours a week and own a house. The wife could be at home to take care of the kids. These days, both have to work 60 hours a week to afford a rental apartment.
in the 70's, a home cost about 4.5 times the median yearly household income. Right now it's about 7 times the yearly income. That doesn't seem like a massive increase (even though it's more than a 50% increase), but employment of married women also increased from 40% to 60%. So while we have, on average, more earners in a household, we pay more of our income on housing. It's a double whammy.
So people want careers in order to start earning a living wage in order to be able to actually raise kids and live a meaningful life in a nice home. People don't just want a career because they want a career, they want that because they don't want to be wage slaves who don't get to live a life. Also, they don't get to raise their kids, because they don't have time for that.
