* lumping 2 decades of people into one group "millenials"
* the younger half of those growing up during the dot-com bubble burst and financial crash
* complete lack in the U.S. of work-family balance policies
A recent study of 22 European and English-speaking countries found that American parents report the highest levels of unhappiness compared with non-parents, a difference the researchers found is “entirely explained” by the absence of policies supporting work-family balance.
Compared to the U.S., Europe is doing a lot better. And, those who can pull off a two-income household do better than those who don't on a number of measures of marital satisfaction.
However this article doesn't explicitly discuss income inequalities in this country, which I think is a huge portion that we must also have on this discussion. It is there implicitly to some extent (e.g. the dual-income comment, but I'm not sure they're necessarily taking into account the very low income dual earner incomes where that's barely enough to survive. Will have to read more in depth.)
Sum up: We really need proper parental leave for both parents in this country. We also seriously need to address this "work for free" mentality crap we've got going on. (<-- this last part is my own addition here, fwiw)
