There are a lot of reasons for the inequality between men and women. I'm not saying they are "justified" or "fair" but there are some obvious (painful, even) but true reasons why men and women don't earn the same. Of course, these reasons do not specify the whole margin but they explain quite some of the variation.
What does it change if the answer is "It is easier for men because they have to put up with less harassment, less pressure and are more encouraged"?
Except this "framing" implicitly introduces the assumption that gendered differences in stress and pressure tolerance is the cause.
Have a look at the death gap!

Note: this is just the first hit on google, I'm a bit reluctant to write down an entire arguement here because you have very like already made up your mind...
"Income inequality" Has been discussed plenty of time, so I'm not going to reproduce it here. In any case, there is plenty of dispute on whether it is the result of "sexism".
"domestic workload" is something society does criticise, but in any case it is a social convention only - not enforced by law.
How about:
- Income inequality
- Unequal domestic workload
- Only 22% of elected parliamentarians being female
