Show me where they 'tripled down', wa. The only way you could know that was if you'd seen a breakdown of what parts of the funds held Enron stock.
There are two possibilities:
Either an Enron employee put all or most of their contributions into Enron stock, or they put only some or none into Enron stock and put it in mutual funds instead.
People who (1) were employed at Enron, (2) took Enron matching shares and (3) spent all their discretionary contributions on Enron shares tripled down.
Those who declined to invest their voluntary contributions in Enron shares did not put all their eggs in one basket.
No "breakdown" is necessary.
If someone used their contributions over the life of their employment to invest in mutual funds, they did not lose all their money.
If someone used their contributions to buy Enron stock they did lose all their money.
The people who are complaining about losing their lifesavings are by defintion the people who put all or the lion's share into Enron stock.
