It's really not possible to compare the economy of Denmark to the US when over half of the individual states have more people than all of Denmark. There are problems Denmark could not possibly face as one country is 60 times larger than the other. Denmark's population is almost completely made up of one color and is historically homogeneous. So many issues they don't have to face... and they like it that way.
Not defending US policy, just stating the comparison is not so simple.
The entire system is built to support us men. It's like an ocean. Women's rights are a tiny artificial sea wall constantly needing work to keep up with the relentless ocean of male dominance.
