Probably my biggest takeaway

I think (most) modern parents are far more accepting rather than over supportive, although that's no doubt an issue, it's lack of acceptance that made these "back in the day" parents really suck. Like most kids, regardless of era, these Source Family Hippies were identifying with the counter-culture, the whole hippie thing was really shocking to the parents. Long hair on kids, psychedelic music/drugs, free love, anti-capitalism: It was so far from traditional values that a lot of kids were disowned, kicked out, given the whole "I have no son/daughter" routine. Modern rebellion is listening to The Ting Tings while wearing a ironic t-shirts, thick rimmed glasses and twirling your handlebar mustache. Your parent might roll their eyes if this is your bag, but you won't likely be disowned.

The Baby Boomers were the young people in the "family" during the 1960'as in this movie, they were the hippies and grunts during the Vietnam Conflict.

They who were born right after WWII when all the young men came home from the Pacific and Europe with the GI Bill, some start up money from the military, a skyrocketing US economy that meant infinite jobs and the young women could stop working and let their husbands take over so they could raise their children, the baby boomers
