Sorry I forgot the vanity tag
Why do you have to respond to some a$$hat who screams at you and calls you names? Is he your supervisor? If not, ignore him. Nothing you say is going to change his mind or bring clarity to his thought processes.
And you could probably predict what would happen: employers would have to jump through endless hoops to do so.
Well, in the first place, it’s an imaginary problem. Women and men earn the same, at the same education and experience levels. In fact, the scale is tilting slightly in favor of women.
However, if you quit work for 10 years to have a baby and stay home with it, your experience level doesn’t match that of the guy who kept working for those 10 years, so you don’t get paid as much.
Simple as that. Childless women earn the same as men.
Explain to him that equality is a fairy tale made up by leftists to grow government at the expense of just about everything that makes a civilization function.
Has your coworker read the bill or is he just acting like a congressman and talking about legislation without reading it?

The Paycheck Fairness Act is as much about Fairness as the Healthcare bill is about health. The health care bill is about control - so is the paycheck fairness act.
The simple reason to oppose this law is that Hilda Solis, Labor Secretary, is pushing it. Read up on Hilda (democrat, CA) and you’ll know what I’m referring to.
The name itself gives it away.
Paycheck... The paycheck is a contract between party A and party B. If either party A or B feels the contract is violated, then A or B may make use of the government to properly be an honest broker in adjudicating this dispute. This is obviously not the case here because this is a legislative Act. See below.
Fairness... In days of old, this term meant that party A, holding power, dispensed this power over subordinate parties, B, C, D, etc., based on a reasonable combination of merit and Godly mercy. Today, fairness instead means that party A, holding power achieved by granting favor to voting constituencies, dispenses this power to parties B, C, D, etc. based on social fashion and the concomitant ability to hold and grow A’s political power. In other words, fairness = favoritism.
Act.... An Act is a piece of legislation which dispenses power. It is not a mechanism by which the government comes to act as an honest broker between parties A and B during their contract dispute. It is instead a mechanism where government PREEMPTIVELY anticipates these disputes, and shows favoritism by dispensing power to one class of party over another, PRIOR to their being any contract disputes.
Ergo, the Paycheck Fairness Act almost certainly is an attempt by a political party to dispense power to favored constituency classes, regardless of real merit, regardless of actual contract dispute, and not with Godliness but with the pretentious ostentation of a faux God, in order to grow a political constituency by the transfer of wealth and property and labor amongst parties B, C, D, etc.
My operation provides thousands of job offers per year. I always chuckle when someone balks at a salary indignantly. Fine, move along. What keeps me honest? If I don't pay fairly, I can't hire the right people. And it certainly doesn't do me any favors to have inequities among staff; it may be poor form to share compensation information, but everyone does it eventually, and if unreasonable disparities exist, strife beckons.
The twist now is that people can file complaints with the department of gender equity or whatever and they will sue the company in question for noncompliance.
