I prefer inequality when it comes to pay because I will work harder than the majority.
It makes it so that applicants can see what all employers are offering up front, which incentivizes the employers to be more competitive on salary offer if they want applicants to choose to apply there.
Salary equality for equivalent positions within the company, as you're describing it, would require companies to publicly list what each of their existing employees are making, which is a completely different thing than what this law is requiring.
Of this whole tangent is mostly a non-sequitor because that's not what the law requires or is an attempt to enforce.
My coworkers are the busiest people on the planet.
