That premium they pay out of SS (<$96.40 monthly for most people) is only part of the cost. Part D premiums are about $30 a month. But most of the cost of Medicare is paid by other sources. See the Trustees Report:
http://www.ssa.gov/OACT/TRSUM/index.htmlHI is paid for by Medicare taxes which the entire population pays in the form of a 2.9% tax on all wages (there is no income limit). To cover about 45 million people, it cost 230.8 billion for HI (part A), and 250 billion for SMI (parts B & D). Plus there was a shortfall of over 20 billion. A lot of the cost is paid from general revenues.
So the total cost in 2008 for 45.2 million beneficiaries was about 500 billion, or half a trillion, most of which was paid for by the non-beneficiary population. 500 billion is 500,000 million, so the total cost per beneficiary was 500,000 million/45.25 million or $11,061 per beneficiary. That is a lot.
Total US population is about 300 million, or about 6 times the current beneficiary population. We would have to spend enough to cover an additional 250 million people. Assuming that the cost to cover the rest of the population would be about half of the cost of covering each older beneficiary, or $5,500 per extra beneficiary, it would cost us $5,500 X 250,000,000, or 1.37 trillion more.
If you had to cover a family of 4 on Medicare, the extra cost would be about 4*5,500, or 20K a year for that family. If you didn't want to raise current costs to Medicare beneficiaries, all of the extra cost would have to be paid by working people. However Medicaid costs wouldn't be extra, so Medicaid could come out of that. Medicaid cost about 333 billion in 2007. We'll make that 370 billion, and say the extra costs that would have to be paid by workers would be 1 trillion.
1 trillion divided by 150 million workers is 1,000,000,000,000/150,000,000 or 1,000,000/150 is $6,666 per worker. So the cost of the insurance would be about 12K for a working family of four. Most families do not currently pay this much for coverage through premiums and employer subsidy, nor do they currently get such good benefits. The average family medical insurance premium is about half this.
To cover this as a wage tax, which would make the most sense, use the 2.9% employer plus employee premium currently. In 2008 that raised about 200 billion (all of which went to cover less than half of the Medicare). Since we need to come up with another 1 trillion, which is 5 times 200 billion, the total extra payroll tax would be 5*2.9% or 14.5% of all wages (no cap). You can confidently expect that total wages would be reduced somewhat because some jobs would be lost and some compensation would be cut, so it would probably really cost about 16-17% of wages, plus the 2.9% of HI tax we are already paying, which would take us to close to 20% of payroll for universal health care and about an extra .5% to cover the lost income taxes. Of course, in a recession year we'd go in a hole, but when times improved there would theoretically be more money on the wage tax, so maybe it would balance out.
It is good insurance, but it is not cheap. Real average costs per worker would rise regardless each year, because the US population is aging quite rapidly. Within another 10 years, figure about another 2-4% of payroll for a total of 22 to 24% of wages. Within 20 years, figure about 30% of wages.
Btw, Massachusetts is currently spending over 6K per person for their covered population, so this back-of-the-envelope calculation really checks out. Also, the equivalent spent in the UK is about 20% of wages.
See, this doesn't solve the budget problem. It would be great right now for lower wage earners, but we would still need to ration healthcare as the proportion of older people rises to workers.
It would be a huge tax increase on higher wage earners. Let's say you earn $100,000 annually. Your share of the health tax would be $10,000 (employer pays $10K).
Your take home wages before income tax (see tax brackets link):
http://www.moneychimp.com/features/tax_brackets.htm100,000 - 16,200 (SS & health tax) =
83,800 - 21,000 (income tax single, no extra deductions)=
62,800 (effective tax rate about 38%)
plus you'd have to pay state income tax maybe of 5%, so your actual take home would be about 58K.
One effect would be that some jobs would be lost, because some employers would not be able to pay the employer share.
