> I never answer questions about my past or expected salary, not to employers and not to recruiters.

That's great for you, but a prospective employer refused to put an official offer package together for me until they had proof of my recent salary.

And no, there weren't other contemporaneous offers on the table at the time, nor were there other employers in my industry whose practices greatly differed from above.

In short, I think this a great consumer protection rule. Not really consumer, but little guy/girl protection rule.
