Not really, where I am full-time employees are legally entitled to a minimum 28 paid days off per year (including public holidays at employer’s discretion) and that’s still low compared to some of the better European countries. My understanding is that the US does not require any paid time off and this petition is to fix that.
3-6 months maternity leave at 66% pay isn’t necessarily great either, here we have 52 weeks maternity leave starting at 90% pay for 6 weeks then the lower of 90% pay or a fixed weekly amount for another 33 weeks. Returning to work in the first 6 months entitles you to the same job, in the second 6 months an equivalent job (equal pay, location, etc). There’s also 1-2 weeks paternity leave for other involved adults (eg father or partner) and the option to share up to 50 weeks of the maternity leave entitlement with them. And those are just legal minimums, for instance my work offers much better paternity leave than just a couple of weeks.
