I think it's more complicated than the article asserts...a large factor is the economic environment, which everyone refuses to acknowledge. Most moral codes are essentially economic, marriage especially, so any analysis should start there.
It's one of the curious inversions of progressivism to talk about rights in terms of groups and collectives, but analyze behaviors in terms of individuals. Hence poverty is always analyzed through case studies of the unfortunate, and case studies of the evil rich, distracting from the broad economic and policy causes such as welfare, inflation, over-regulation, and taxation.
This is an old playbook which is becoming increasingly reminiscent as modern US journalism converges to the Soviet journalism. Step one, avoid drawing attention the economy, or economic suffering. Step two, if you have to talk about it, distract by making it sound like a feature, or making it sound like it's not really a problem. Certainly not a fundamental problem with socialism/progressivism.
Real wages have been stagnant for generations, manufacturing jobs are gone, pensions are gone, and unemployment is high. When young people find it necessary to move regularly just to chase the few decent jobs left, it's not desperation. It's just the millenials are "the go generation" and "don't feel tied down to their hometowns like previous generations".
When the American dream of owning a home and car is out of reach of young people, it's not evidence of an economic crisis. It's just that "young people today are choosing not to own a car" and are "significantly less likely to tie themselves down with home ownership, preferring more flexible living arrangements".
When the average age of female childbirth, and male parenthood, are both at record highs, it's not because young people are graduating with crushing debts that don't actually increase their earning potential, and both of them have to work to make the same standard of living that their parents had with only the man working. It's not any of that. It's just they are choosing to get married later because of changing attitudes about sex and internet porn...not that the willingness to shack up and the porn epidemic are the result of dire prospects for successful marriage.
These aren't the droids you are looking for. Everything is paradise in the Soviet union. American Progressive politics work.
