made a very conditional statement. I didn't assert anything that needs to be "proved."

I didn't say you did. I was also making a response to your statement, just like you did to the post before yours. Namely:

It's not clear (to me anyway) that layoffs are per se a bad thing, individually or in the aggregate, if the reason for them is that companies are increasing their efficiency in producing goods and services at a profit.

...pointing out that there isn't any indication that the specific condition that you provided under which these would be the good kind of layoffs is, in fact, what's happening. I would also point out that while some layoffs might be for good reasons or signs of economic health, as a very general matter layoffs are more often associated with negative economic factors than they are positive ones. For the simple reason that growing, vibrant, and healthy business are generally less likely to affirmatively lay off workers than sickly, contracting, or ending businesses are.

This isn't "concern trolling." It's a discussion - one person says something in a conversation, and another person follows with a statement relating to what they said.
