I find it interesting how quickly people jump to 'but have you thought about damaging it is for children?'.
As with everything, done right, polyamory has no reason to be any more damaging than raising your children with monogamous parents, other than the fear of judgement''
What you are saying is simply not logical.
If you look at it from a purely practical point of view people with several partners will have by definition less time to spend with each individual involved in the relationships and with their kids.
If you had kids to support as well with each partner, it would means less disposable income for each family.
You also assume that the kids will be happy to share their parents that way and see less of them because they choose to have several lovers or to have to explain in the playground why their parent has several ''official'' partners.
I have met several poly people and never seen it work in the long term.
The majority ended up moving in with/getting married to a single partner and having occasional casual sex (both sides agreed to an open relationship). They dropped the pretence that they were managing to have several equally loving and emotionally committed relationships at the same time. They simply wanted some variety of sexual partners which at least is an honest take on it.
Others lost their marriage over it or/and fell out with their kids, when the kids were old enough to understand what was going on and they simply did not accept their parents' lifestyle.
So frankly this is not about moral judgement it is simply looking at the reality of these relationships and the impact they have on people rather than the trendy gloss that is being put on them.
