Somewhere in the comments is the observation that people who talk about the wonders of the family of the past tend to stop dead when asked to specify what year they're talking about. Small wonder.
People want to live in a hypothetical, broadly sketched, past with all modern conveniences. They want to be rid of seatbelt laws, but probably not to drive a 1950s car, even a brand new one, but without the air conditioning or the modern brake systems. They want to use rollerblades without helmets or kneepads, not the old-style roller skates you attached to your sneakers with a key. And, of course, they want the Internet, cheap long distance phone calls and affordable air travel, and such.
The past is a foreign country, and they don't have tourist facilities.

It's not really the same thing, but if I got the chance to go back in time to my childhood with at least a modicum of what I've learned, I'd grab it in a heartbeat. Roller skates and lead paint and all. I'm not really unhappy with my life, but an awful lot of what I regret dates back to then.
