Only it doesn't really work like that. A lot of the employees would have been innocent. Secretaries, lab workers, mechanics, janitors, scientists. These weren't risky ventures, they were a job. While they might have been able to leave at any time from a legal point of view, not all of them would have known that it was that risky. You know, because it is a job. It is a bit different if you are investing money in it, getting paid less, and so on.

And lets not forget this wasn't really a small operation: Over 300 employees. Multiple cities.

And the government does do some things to protect workers - such as unemployment and labor laws. But again, this is different than protecting risky investments. I'd even argue that this is partly the governments job by requiring disclosure of known risks and by prosecuting folks taking advantage of others - the rest is the discretion of the money holder.
