If the healthcare is given by your employer then you have single payer.
Wrong. Employer provided healthcare is not single payer coverage - not all employers have the same coverages, deductibles, or other options such as vision or dental included. Some employers pay 100% premiums, some pay 50% of premiums - whatever is realistic in their budget. You don't HAVE to participate in the employer's plan - your spouse may have a much better plan through his or her employer whether or not both employers have coverage with the same carrier or different carriers. In either case, you likely have the option to have PPO or HMO coverage - whatever suits your needs best. Most people choose HMO coverage because of lower premiums, lower deductibles and no further obligation to pay the balance of what is owed on the medical bill - and you have to choose from a network of doctors and hospitals specified by the carrier. With the PPO, you can go to any doctor you wish, pay a higher premium, higher deductibles and you are responsible for any costs over and above what the insurer will pay - that's usually an 80%/20% proposition.
"Single payer," as used in "Obamacare" is defined as the government being the only entity that offers coverage to all people - all wrapped up in a nice little lie that nobody will ever be denied coverage for any reason.
Under Obamacare EVERYBODY has to be covered - there's no choice in the matter. Fact is, bureaucrats and their "experts" will decide whether and when you receive medical treatment - it's not a matter of you WILL NOT be denied treatment - you WILL be denied treatments or surgeries based on a number of factors - "one size fits all" rules and regulations mentality as is currently practiced throughout all government controlled departments or agencies, your age, your general health situation and so on. You're going to have fewer choices of physicians because a lot of them will give up their practices leaving a smaller pool of doctors. It may take weeks or months before you will be seen by a doctor and will probably not see the same doctor twice because there will be a shortage of general practitioners, fewer surgeons, fewer specialists, fewer everything.
What America has today is a system where we can choose our doctors, can usually get an appointment within a week, we enjoy a personal relationship with the same doctor all the time - he or she has an intimate and informed history of our healthcare issues. Specialized physicians can be seen relatively quickly; surgeries can be scheduled within days; we can have elective surgeries just because we want it and can afford it. We can kiss all that goodbye under Obamacare.
Are some people in the position of not being able to afford medical care? Sure their are - it's sad, but true. We currently have Medicare and Medicaid to cover those people - and look where that's gotten us financially. Emergency rooms are not going to turn anyone away because of inability to pay. If we think emergency room waits are irritating and a pain in the ass now - just wait - under Obamacare it's going to be even worse.
Government has no business whatsoever being involved in making healthcare decisions for us - that should be a decision between a patient and his or her physician. Period.
