Suds and Launderess:
I think it's important to remember two things about the Joan/Christina saga:
1) Joan was herself an abused child, regularly beaten and from a family of drifters no better than they had to be. Abuse is a cycle, and with the best will and the best help in the world, it is a difficult cycle to break.
2) The 1940s and 1950s were not our era, not by a long shot. It was absolutely unheard-of to discuss "family problems" even with fairly close relatives and friends - the social norm then was to keep a lid on everything and present a perfect facade to the world. I well remember the tail end of that era, and when I recall it, it's with shudders.
From today's more enlightened perspective, it's very easy to do some Monday-morning quarterbacking and say what should have been done in this situation. But we were not there, we were not part of that culture.
Joan screwed up, okay? I am not denying that, not for an instant. She did abuse Christina. But that was one story among many - like the abandoned Pickford kids, Ronnie and Roxanne, cut off by Mary when they turned out disappointingly. When last heard from, Ronnie was homeless in Manhattan; Roxanne is dead after years of untreated ill-health. The Pickford mansion, Pickfair, fetched over $5 million (from Lakers owner Jerry Buss) when sold after Mary's death. Ronnie and Roxanne didn't get a dime.
Movie stars really shouldn't have kids - natural or adopted - during the years they're on top. You say that Joan was self-centred, but that's the job description, folks - if you're not self-centred, you probably won't make it as a star. You have to promote yourself and bring yourself to the public's attention ceaselessly. It doesn't leave a lot of time or emotional energy for anyone or anything else, and I have long wished that more stars recognised that.
I have to wonder if today's star adoptions, like those of Angelina Jolie and Madonna, are going to be the fodder for sensational stories in the year 2030 - are those kids' lives as star babies going to be the horror stories of tomorrow? Time will tell.
