I fear that OTB is judging privatization based upon how he, and people like him, would fair. OTB, I would venture, is wealthier, more educated, more sophisticated, and better able to find ways to fend for himself that the avergage (or less than average Joe). Good for him!!! I really like listening to his point of view.
BUT, while the notion that people can better do for themselves - and learn how to better do for themselves - is laudable - and more ways to instill such things should be found - something like this change is so important and so sophistcated that notion of acceptable risks is the last part of the analysis. You should only get there after you have explored all other alternatives. And even after you have found that this is the only workable alternative, you still have to understand that no risk is ever really eliminated. The least change in the basic structure is the best way to proceed. The problem with modifying the present structure, is that the people most affected are alive, well, and want to pass the costs and risks of the present system - which does need reform - on to future generations. Politicians have a hard time with selfishness and fear by the voters now. If is better to promise a better system later and tell them that it makes sence by lessening the finacial burden by paying for the transition now. The way to pay for the problem is to increase the retirement age, stop the borrowing by the Federal government with US debt instruments, and means test SS payments after some specifed minimum guarantee.
Then after you have premitted the SS administration to get away from US debt instruments, you consider incentives to increase the savings rate. Probably another type of IRA - and particualarly if they do away with tax on interest and dividedends, consider a tax subsidized IRA with more subsidization going to lower wage earners. THe more money you have (make) right now the better able you are albe (up to a point) to shelter it; this has to be considered.
