What benefits me most is having the choice to have or not have insurance at all.
If I choose to have insurance it is to my benefit to choose which plan I deem best for me at that period in my life, what level of coverage I desire to pay for and which of the many insurance companies I want to go with.
When the government runs things they ALWAYS screw it up! Social Security is a prime example. A total screw job. Government health care will be similarly messed up.
At least with a private insurance company I can switch companies and/or plans. Private entriprise is always better than government services.
