Also, this 'equality' approach _reeks_ socialism to me, and, coming from a country that suffered from socialism for 70 years, I have seen with my own eyes what disastrous economic effect this has on the workforce.
In theory, equal wages lead to more just distribution of wealth. In practice, they just destroy productivity. In the USSR, people had _extremely_ low productivity because life taught them that no matter how hard they work, they'll get paid exactly the same as the most lazy useless colleague who does absolutely nothing all day long.
Salary is a price that a person is willing to sell their work for, and if they are not happy with what they get, they can ask for a raise. If it is not given, it is likely because the work they are doing is not worth it. But they are free to look elsewhere for a bigger pay.
