I actually understand both sides of this debate.
On one hand, I can see how the OP would have been taken by what they heard, especially if the layoffs & vacation were mentioned in the same conversation. I would've thought it was pretty sleezy myself if someone told me they did/were doing the same thing. Just doesn't come out right.
On the other hand, like it's been reiterated before, the separation of business funds & personal funds ...yadda yadda..we've heard it.

But it's true though & makes a valid point. If all of us stayed home and waited for everyone else to be taken care of before we spent $$$ on ourselves...this country would be completely ruined right now.
So it's easy to see where both sides are coming from this time. Any employer who hands out a layoff slip realizes what type of environment they are sending the now-unemployed out into. It ain't pretty. I don't think any employer with an inch of human emotion finds pleasure in doing this to others. But this economic climate is making that tough decision so inevitable for so many small business owners. Like the person encountered by the OP, they had no choice.
So who's side is right in this debate? I honestly can't tell you. When it comes to tough issues like this, I stick with Suze Orman's motto:
"People first, then money, then things."
The problem is, this country has it in the order of #2, #3, THEN #1. And thus, we find ourselves in this nifty little recession we're stuck in.
What the small business owner could have done was take a smaller, less expensive vacation, and use some of the leftover $$$ as out-the-door bonuses for the individuals he's having to send out into the 6-1 job market. Could've made the difference for them & their families when it came to a month's worth of groceries. And when the recession is recovering, then he could start planning a Vegas trip. Given the circumstances we're facing today, I'm sure his wife would understand and appreciate the kind gesture. Just a thought.
