I hate to do this, but
Those things that you cite as having been lost have nothing to do with comprehensive social insurance. Civil liberties and social insurance are orthogonal.
Not here. And not there.
You have civil liberties that are different from ours. Part of ours is a serious belief that our personal and medical information is VERY private. We get to choose who sees what. Of course, this crumbles when you have a medical issue that is dealt with via a large insurance company, but that is part of a required process that an individual agreed with. But some people don't agree with it.
Some people see that once their medical information is part of a vast government database, then a huge portion of unknown people will have access to it.
And they are being forced to join this. If they don't, then the feds will be allowed to fine them some serious cash. And don't bother talking to me about the various support they can get, that's just one more tool for the omnipresent (and possibly malevolent) government to get their hooks into you.
These a reasonable fears. Who among us (in the IT / database side) really sees a correctly designed and administered field by field, record by record, ACL protection system, with each VIEW (as well as modification) of each record tracked, and any abuse of system by any employee (including simply reading a record that is not part of their job) gets them canned and possibly prosecuted.
Not me. I see some minimal multi-tier security. And it'll end up that the help-desk functionality gets farmed out to india, with the ability for them (really, any random IT guy) to suck out the whole database and sell it to the highest bidder.
And that's just one of many examples, they really just go on and on.
