The insurance safety nets that are referred to in Ontario, in the United States, and in other places have been put in with the very best intentions. In practice, it's been a very big challenge to make them work successfully. For example, every time a large employer is on the brink of bankruptcy and it threatens to wipe out the pension guarantee fund, you've seen that governments--the Province of Ontario, the Government of the United States--have to step in and take other measures, because the collapse of a large plan would completely wipe out the relatively small safety net fund that has been established.
I would say the actual experience with these safety net funds has been challenging. For them to work properly would require very high tolls paid by the other pension sponsors, higher than what anybody has been willing to charge today. That's the nub of the issue.
