First off, Medicare is the very definition of a socialized program. Its a government insurance program for the elderly, financed through payroll taxes levied on Americans still in the work force.
Secondly, as to why seniors many times get Medicare supplements. If you are insured either through an individual policy or a group policy through your employer, then you of course have some gaps in coverage with your policy. For example, you almost certainly pay a copay when going to the doctor (usually around 30 dollars a visit), you have a deductible, you have a coinsurance of around 20% to 30%, and you have medical services that are simply not covered.
If you are young and in good health, you probably do not utilize medical services that often. At most you are probably getting an annual check up and visiting the doctor in the rare event you get sick with strep or something like that. So the gaps in coverage under your insurance policy, things like copays and coinsurance, are not a big financial burden for you in terms of out of pocket expenses. In the event they are, then generally you would just sign up for a flexible spending account through your employer and thus set aside a small portion pre-tax each pay period to pay for out of pocket expenses.
Medicare is just like your insurance that you have now, it has copays, coinsurance and so on. However, seniors utilize medical services far more than younger people do. So those copays and coinsurance are much more of a financial burden to them. Moreover, as they are retired, they do not have the option that workers have of setting up a flexible spending account. As a result, many of them opt to purchase a Medicare Supplement to cover the gaps in Medicare coverage for them and thus limit their out of pocket expenses as much as possible.
Seniors love their Medicare though. That's why these fear tactics that some on the right are engaging in now are so effective with them.

What makes you think they are telling the media everything. They have no obligation to do so. Since they are aligned with SEIU/ACORN they are in fact in support of the HR3200. They said they are not in support of any bill. That's a lie. They can obfuscate that there's no bill yet, but bottom line they had Obama on an on-line townhall, fed him softball questions he had obviously agreed to and allowed their forum to be flooded by administration agents (ACORN). Can I prove ACORN was there? Nope, but I was there and that's what happened in my opinion.
They may be representing labor or the communist party but they are certainly not representing senior citizens.
