I would expect no less for the majority of companies. If you put in X hours for Y salary/wage I don't doubt they'd give the same amount as compensation regardless of sex, age, race, etc. Money is money and work is work. Social norms are the real culprit in terms of inequalities in society. Sometimes businesses do push back against these norms since more often than not it hurts their bottom line (ex. racial segregation laws hurt the private bus companies). So, if a social norm can be toppled to boost revenues or productivity I always expect a business to wave their progressive banner.
