Thats why, when divorcing in Switzerland, retirement savings are bundled and then split equally between two. So if woman was a stay-at-home mum, she still gets good savings. If both brought cca same income, not much changes.
Changing divorce laws to be less equitable, as far as I know, has never been a major platform of either party in the South. I'm not aware of any politician that advocates for it. I'm sure it exists but it must be an incredibly marginal view.
