I will also not have a child and live in an EU country where parents get a lot of paid parental leave. I think it's great. Why wouldn't I want to work alongside happy, less stressed coworkers who aren't constantly _extra_ sleep and energy deprived from worrying about having to unsustainably juggle work and kids? Companies are well aware of the laws and know they need to staff appropriately. In addition, it is a good thing that parents get to prioritize their children because it makes for well adjusted children for us all to live with as they grow.
As a person without kids I do sometimes wish childfree people got benefits in ways that have more _immediate_ applications for us as well. But that doesn't mean parents shouldn't keep getting generous leave allowances to care for their children.
