I dislike the idea, but am I just being selfish in objecting to it? (Obviously this type of thing means rich/tall/strong/good looking guys have multiple girls while most men would go without.) If the girls are happy the only being 'hurt' by this are less appealing guys, which is pretty entitled of us to be bothered by it.

Well, it's their relationship so it's really none of anyone else's business. If it's consensual and everyone involved is happy with it then there's nothing wrong there.
I disagree with the idea that 'less appealing guys' will be hurt by it. Your assumption seems to be that the girls would 'settle' for someone they weren't attracted to if the guys they wanted were taken and not open to polygyny. I don't think they'd choose to be with someone they weren't attracted to regardless, if they couldn't be with someone they found 'appealing' they would just stay single. So it wouldn't make a difference to 'less appealing' guys
