How do you ensure equal opportunities in your team?

It will sound like something from prehistoric times, 😀 but in my country, the vast majority of employers give women lower salaries than men. Fortunately, I don't feel it that much because I work with foreign clients, but I don't think it's fair.

(But we probably all know why this is the case – less is invested in women, because it is expected that they will go on maternity leave one day and therefore have no prospect of staying in the job longer compared to men, where the continuity of work is higher)

This article gives me another example of injustice.
TL;DR: DJT is warning big companies and not wanting them to hire Indian workers.

I am curious: how do you make sure no one is disadvantaged in your workplace due to race, gender, religion, origin, or other personal factors?

And what do you do when a "higher instance" wants you to stick to some kind of inequality?
