It's part of a broader Trad-con movement. Basically people, typically in their 20s or very early 30s that have a desire for a modernized version of the romanticized 50's lifestyle. Conservative Christian values and morals. Patriarchal family structure. People actually being responsible and reasonable financially (Saving and working towards financial freedom through investments rather than being a fad chaser). etc. etc.

As I said, the image of young people being kool aid haired hyper liberal freaks is just a media illusion. They do exist, but they're vastly out numbered.
