It's not a matter of 'hot topics' or 'politicization'. Workers demands for fair compensation in general have a long history and are a central part of the relationship between employer and employee. If you think the fact that siblings might experience different economic outcomes has anything to do with this, you've (most charitably interpreted) misunderstood the topic.
Violence on the other hand also has no place in the work environment. Which is why harassment of all forms isn’t tolerated.
