There are very strong lingering effects which mean women, on average, are paid less.

It's especially hard on women in various countries where they're now expected to both have a successful career and be the primary child caregiver. Which is as ridiculous as it sounds.

However, one example of advocacy from a cafe in my city of Melbourne Australia a number of years ago really rubbed me the wrong way: when a cafe decided to charge like 25% more to men (inverse of 80%). I was a close to minimum wage worker at the time (in Australia, before the cost of living skyrocket, so I wasn't starving), and it annoyed me because if I went in, I would be asked to pay more because I was a man, never mind the fact I would likely be earning far less than many women going in there.

The wage gap is 100% real, and things should definitely be done to make all genders pay more equitable. But hell, the class divide is orders of magnitude worse, and we ought not forget it.
