Social Security is a disaster. Most people earn less than what they would have gotten investing the money themselves. It's a pyramid scheme. It can't ever be ended, because the current retirees who would be cheated would vote against it.

Medicare and Obamacare - another disaster. The reason healthcare is expensive is because the AMA and government limit the number of seats in medical schools, keeping the supply of doctors artificially low. Everything else is just a band aid working around that problem.

Employer-paid health insurance is another disaster. It means that most people aren't paying directly for their doctor costs, so there's no incentive for anyone to compete on price. It also means that anyone unemployed is screwed, creating the need for something like Obamacare.

If you want an example of how big of a disaster the healthcare system is, try having a pet and paying for a vet visit. You're paying out of pocket and it's much cheaper. For the most part, it's the same types of treatments they give to humans. That's because the AMA and other lobbyists haven't inserted themselves into the system.
