My children would then have to take care of old people in this situation at some time in their life, and my grandchildren would also have another set of old people with no money to take care of.
I know it sounds grand to be able to plan for your own retirement and not have the government tell you to do it, but that only works when everyone is able to do the same. Perhaps Republicans are not concerned about others, why they don't even put that in their calculations when they are thinking of doing away with SS.
And, privatization is not a secure option. If people on retirement during the Bush meltdown had put their retirement into a private company, chances are they would have lost it all and we would have a lot more people on food stamps and welfare. And we know what happens when private companies get greedy and end up bankrupt - the people that trusted them are the ones that end up losing.
