Enron was an company run by honest men, with honest accounting, and it ran into the ground, that would be one thing. Ken Lay and his enablers lived like kings, defrauded their workers, and played on their sense of loyalty with lies to keep their fraud going. This was criminal, and ruined thousands of workers' finances. So yes, you should "feel sorry" for honest, working people who believe their employer and put their earnings into a 401(k) plan, touted by their company until it collapse due to fraud. Even if they should have been better-educated about investing, and more skeptical of management and accounting they are indeed victims here.
Oops, I meant, "IF Enron was a company run by honest men..."
Of course they are - but they made themselves victims and that's the key distinction.
Anyone who handled their retirement finances like a responsible adult should could not have been significantly affected by Enron's collapse unless they wanted to be.
