Here’s another thought: they’re broke. Granted, that’s not as sexy for magazine writers to talk about as sussing out cultural and demographic trends. But it’s awfully hard to buy a house or a car when any of the following apply:

• You are in student debt up to your eyeballs.
• You can’t find a job.
• When you do find a job, that job is insecure, low-wage, with few to no benefits. 

Yet pundits are constantly exploring the choices these young people are making as if there is some great mystery to be divined. They aren’t getting married! They’re still living at home with their parents! It must be because they are lazy, or immature, or indecisive, or turning away from consumption for ideological reasons.
No, they just don’t have any money. And money is what you need to do stuff like get married and set up your own household and buy expensive items.
