It's no more an expectation than anything, it's a hope that old age programs will be there when we are old, no more or less irrational that the hope that the 401k won't tank.
Everyone relies on others. I guess maybe the ideal of a person not relying on others would be single (of course), have thier own health insurance, not take any help from family ever (not for education, not in hard times), never take a government loan, etc. etc.. They are unlikely to ever be as sucessful in this economy as those who work with others toward their goals because the gains accessible to the average person will actually accrue to those who can best maximize opportunities (sometimes to those who exploit others but I don't condone that) and not to those who can be the purest most unsoiled examples of individual self-sufficiency but ... thems are the breaks. By the way I'm a pretty good example of self-sufficiency
threatening is an expression of disgust with the policies, just leaving might be out of nothing more nor less than rational self-interest.
an interesting theory and a very poor map of current american reality. A few social programs exist which serve the majority, and they probably won't survive unless they also produce corporate kickback (any programs which don't produce corporate kickback are precisely those under attack!), but much is also done to benefit a select few. Who? Every Homeland Security profiteer out there, Blackwater, the banks that were propped up by government policy, the government coverering up for BP etc. etc.
what prediction, descent into dictatorship? Where does Paul Ryan even stand on civil liberties issues? Oh wait those have nothing to do with dictatorship, the real causes of dictatorship are mostly Medicare and Social Security, obviously (sarcasm). I think a way way stronger case can be made that the descent into dictatorship is caused by EMPIRE, and currently a very clear case can be made that the civil liberties violations are DIRECT assaults.
