I disagree with your last bit.
>'Given the extreme change we are going through, the “if you can’t handle it, don’t have kids argument” is just not realistic. A pandemic isn’t “just how life goes”.'
Maybe not a pandemic but it shouldn't be any shock that children make things much more complicated. It's, most of the time in the US today, a choice to have a child. The unexpected nature of a pandemic isn't really an excuse for me. One knows unexpected things happen with children, if you haven't prepared for those unplanned contingencies, that's on you as a parent. Should the same benefits be given to parents who maybe have to stay home more because they feel their kid a slightly larger burden than others? What if the child becomes autistic and you are required to spend more time with them?
Any situation like this sucks but at what point should it really be a businesses problem and when shouldn't it be? I think these are really interesting problems under normal circumstances, the Covid part is just businesses having to deal with them all at the same time rather than individually on a case-by-case. To show that this isn't just Covid, let me share with you a story about a few nurses I met who have been exploiting a hospital system for personal gain (and brag about it!), something that could ruin a small business with relative ease.
Big hospital near me has a policy of maternity leave for nursing staff, something like 6 months off, no questions asked whenever you have a child. Sounds fantastic on the surface. Well, this small pack of nurses all knowingly do the same thing, they have children as much as humanly possible, think on the order of 8-13 children. Because of their constant pregnancy and child birthing, they are effectively able to work only 6 months out of the year, 6 month vacations. Everyone else at this org, maximum time off in one stint is 3 weeks. This means, under this hospital's policy, the only way that I can take a month off is to either work at least 1 day each month. Say goodby to taking months of in winter to stay in warmer climate, say goodbye to benefits otherwise. These nurses though, who are easily able to save their salaries to cover their yearly costs, get all company benefits like healthcare. Is this 'fair'? As someone who isn't physically able to have children, I would argue no, it's not completely. This isn't to there should be nothing for these parents, I don't really know what the right answer is.
