I work with a lot of young people, both volunteer work and at my day job. Despite what this article says, there are a lot of young people who still want a spouse, family, a house with a yard. A lot of this depends on where you ask the questions. You go to NYC or LA and ask, and you'll get a lot of career driven young people who are completely focused on career, advancement, and money. A spouse may be an accessory to go with the suit they wear to parties. Kids may be an accessory at the company picnic, or frankly an unnecessary expense with no return on the investment. Go away from the big city and you'll find young people who are less about the career as the goal, and who value family first.
That said, I also overheard a group of college guys while visiting my son. A girl flirted with one of the guys, who blew her off. The other guys razzed him about blowing her off, asking why he doesn't want a girl. His response: "I've got the internet. I can shut it off when I'm done, and there's no drama when I don't call tomorrow."
