We need a system with co-pays, not 'free'. Also, if someone elects to seek treatment privately outside the Medicare Plan, fine, let them. No punishment to them or the provider. It's their money.
Because I have been self-employed for past 25 years, I have been battling our current system that long. It sucks! Allow me to buy in to Medicare, even if they pro-rate me due to age, I'd grab it in a heartbeat. Anything is better than private healthcare I can no longer afford.
