This is how consumer- and market-driven capitalism works. Every individual in society is turned into a consumer, male and female, young and old. But to be able to consume, you need a disposable income and to get that, you need a job. Today's society regards every individual as a potential consumer.
Of course, some women are still baby-making machines. Some boys and girls lose their virginity at a young age and become teenager fathers and mothers. I have met quite a few teenage fathers lately and I wondered, what is that guy doing with a baby?
The politicians and economists deliberately structured the economy so that some of us would be adolescent child-bearers (the ones who cry out, "Honey, we're pregnant!" at a young age) and the rest of us would be career-focused mind-labourers (scientists, engineers, accountants, teachers, academics, office staff). I will not neglect to mention the technicians and tradespeople. They are in this as well.
The latter kind are the mind- and slave-labouring consumers who work to spend. They make money but can't keep it because the politicians want them to spend it. They have to spend because they envy their neighbours. They see other people in their society enjoying themselves and want what they have. Everybody is competing against others to live ever more luxurious, glamorous and extravagant lives. It's a "shop till you drop" society.
This is why people don't have time for kids. They are too busy aiming for the life of extravagance. They want a house of their own and get a home loan. Their money goes into paying off a mortgage or rent. I think it would have been better for them to just live with their parents. Why buy a home or pay rent when your parents can share their home with you?
Why do people keep sinking money into something that costs several hundred thousand dollars? That is a thousand times more than a computer. Most people could live on a computer, food, water, pens and paper, a television, a phone and public transport. They could do all that if they could live with their parents.
But the politicians, economists and lawyers are betting on you leaving the home of your parents and buying your own home. There is social pressure that compels people to do that. You envy your friends for living separately. Being able to live separately from your family is an achievement. So out of shame and embarrassment, people choose not to live in the same home as their parents.
Nick_the_Pilot, you live in China. You must be aware that traditionally, the Chinese used to congregate in large families. The idea of leaving the home of your parents and living separately from them is something that has become popular in modern society.
People in poorer countries wouldn't mind sharing rooms with five or so people. They're used to it. The modern Western individual has a "big life" (so to speak) that requires that he/she exclude others from their living quarters. He/she has a room all to him/herself. The life of the Western individual is "bigger" than those in poorer countries. I think the life of the Western individual will continually get bigger. Contentment will become an ever more elusive goal. Bigger is never enough.
The younger generation can have a better and "bigger" life than the older generation. It is easy to get that life when you're a kid, but when you grow up, you have to work for it and nothing ever satisfies completely. You work hard to find that "bigger life" you envisioned as a child at the expense of your children. That is why children always suffer.
Western countries already have the technology and economic strength to feed all their citizens, but because life keeps getting bigger, people keep having to work hard for something they don't really need.
There is a good reason why many Western countries have a trade deficit. They already have too much. They consume more than they produce.
