The postal system is going bankrupt because of a change in the way we use it. It was a viable and successful organization for a couple hundred years, but you could say the same about all the village blacksmiths, too. Times change. Technology changes. What once made sense, makes sense no more. However, the postal system isn't dead, it's just transitioning to a new model for the new age.

As for Social Security, the concept was good, the law was good, but politicians were given the keys to the lockbox, and can't stop raiding it. This actually happens to every similar system that I am aware of. When some revenue is dedicated to a certain objective, the politicians can't stop dipping into it for other projects. Doesn't matter which party, either. However, in the case of Social Security, to answer your question: Yes, I think I will collect. Perhaps I am older than you think, but Social Security will not be allowed to collapse before I have collected. The piggy bank was raided by the piggys on both parties, but they left IOUs that they will feel obligated to repay for the same reason we pay on the national debt: The alternative is unthinkable to the politicians. The only way that Social Security will be abandoned, and all the seniors who count on it cut off, is if the Rs do it, and they won't.

On the other hand, this is just another case where everybody discussing the issue is too young to have a personal memory of the situation before Social Security. Just like the anti-vaccine people who link vaccination to all kinds of other issues, it's a worry they can fret over because the greater worry that vaccination solved is no longer a concern. In this case, however, most of you know somebody who receives Social Security. Sit down with a group of those people and discuss how their finances would look if the program were to end tomorrow. Then consider what this country would be like without it. If that alternative looks good to you, then either they lied to you, you didn't actually talk to them, or your medication is a bit too strong.
