That's a large part of it. It's especially works well to get rid of people who are older and have families, and keep mostly fresh college graduates and singles. And those usually have a lower salaries, we're getting fresh employees who are lower cost, everything looks great on paper.

Except that the first people who would leave might also be the good experienced engineers, but that loss is a little hard to see on paper at first, to predict and so it doesn't get accounted for very well.

Yep, it's just a backdoor layoff.
