We've entered a transactional phase where your partner is supposed to show up perfect, well-adjusted and no work on your part for a healthy relationship is required. Not working? Ditch 'em and try again. That's the other extreme, sort of the exact opposite of staying due to social pressure with someone you hate and makes you unhappy, and it's also unhealthy.
Do you feel like there's a good way of measuring whether a relationship is worth saving or not?
kinda depends on what you're looking for in a relationship. all relationships take some level of effort and compromise to maintain. however you measure the "value" of a relationship, it has to at least be better than being single to be worth the trouble. I'd say a relationship is worth saving if a) both partners agree it is better than being single and b) both are willing to take on a roughly symmetrical share of the effort and compromise.
There used to be pro-familly policies in USA that basically assumed that is male is in the house, the male is responsible to be breadwinner. That meant that if there was make, woman would not get social support money on her nor on kid.
They were even quicker to kick unemployed male out due to that - his presence meant they risk support. It sucked, imo.
Kids end up in foster care for many reasons, and its not necessarily because their parents are violent and abusive. The ubiquity of single parenthood, for example, dramatically increases the risk that a child will end up in foster care if anything happens to the remaining parent. Likewise, in a society where divorce and single parenthood are ubiquitous, other members of the family are much less likely to be in a position to take in a child when something happens to his or her parents.
I'm not suggesting we do away with social workers who can check in on kids in abusive situations. To the contrary, if social workers weren't overwhelmed taking care of a large number of kids who are in challenging circumstances simply because their dad doesn't feel like being a dad, or for other mundane, solvable reasons, they would have far more attention and resources to devote to kids suffering from alcoholism, physical and sexual abuse, etc., in their families.
I grew up with my parents married. They were married before I was born and are still married now. That didn't and doesn't stop the abuse, the mistreatment, the violent rages, the substance abuse, the mental illness, or the cruelty. I wished every day State authorities would come take us away because the alternative couldn't possibly be worse than this. They never came and I never had the courage to tell anyone. I just had to suffer.
The system failed me badly, but it would have failed me worse if the authorities did come and said "well your parents are married and you have food to eat and a bed to sleep in. Looks good."
