The Cost of Living

Recently, I've had a few friends either quit or lose their job. I like to hear their plans and hopes for the future as well as their concerns in the present. I have found that there is one common source of worry. It isn't paying for their house or buying food and clothing - Inevitably, the question they all have is: How will I get health insurance for me and my family?

For an average health care plan purchased individually (Not thorough a company), it is very normal to pay $600-$800 per month. A friend who lost his job told me that COBRA health insurance for him and his family of 4 is $1,600/month!! Needless to say, he is very concerned about finding a job.

Health expenditures continue to grow very rapidly in the U.S. Since 1970, health care spending has grown at an average annual rate of 9.8%, or about 2.5 percentage points faster than the economy as measured by the nominal gross domestic product (GDP).

The question is - Why does health care insurance cost so much?

To find the answer, we have to understand the real drivers of Health Care costs. There are of course many theories and rumors:
-Malpractice
-Smokers
-Cost of Emergency Room care for uninsured
-Beauracracy

While these factors certainly impact the cost of Health care, most Health Care experts point to one primary cause - Medical Technology.

New drugs, technologies, techniques, and so on are developed at great expense by pharmaceutical and biotechnology companies. The costs of developing many of the current drugs and technologies frequently runs in the billions of dollars. Those costs must be passed on. In addition, doctors who are skilled in innovative surgeries and techniques are in high demand and can charge almost anything for their services.

We must also not forget that most Hospitals, HMOs, Private Practices, Medical Technology companies are run for a profit. They are businesses attempting to provide a valuable service and be compensated accordingly.

The ever increasing array of medical services that patients demand is clearly a driver of Health Care costs. But are all people entitled to all new forms of medical technology? This is a complex political and ethical issue, which is not likely to be solved anytime soon, if ever. In the meantime, we can expect Health Care costs to continue rising and more people becoming uninsured. The alternative of Socialized Medicine that is proposed in one form or another has its own problems, so I can't see any easy answers.

How Much Does it Cost to Write This Blog?

So how do I figure it out? For starters, here's what I need:
1. A laptop - 65W
2. A router and modem - About 10W combined
3. Internet connection - $19/month

How much does it cost to keep the power on? Well, it really isn't that difficult, but it will take some explaination...

The rate of electrical use at any moment is measured in watts (from here). A light bulb puts out 100W, a computer maybe 200W, and a phone charger about 3.75W to name a few.

Electricity is billed by the kilo watt-hour (kWh). What is a kilo watt-hour? One watt-hour is the energy used by a 1 watt device running for 1 hour. 1 kWh equals 1,000 Watt-Hours. So for the examples above:
- A 100W light bulb on for 10 hours: 100 x 10 = 1000 Watt-Hours or 1kWh
- a 200W computer on for 10 hours: 200 x 10 = 2000 Watt-Hours or 2kWh
- a 3.75 phone charger on for 10 hours: 3.75 x 10 = 37.5 or .0375kWh

The cost of electricity varies widely by location and even time of year and time of day. I'll assume a cost of $0.12 per kWh.

So for the same items, we have:
- A 100W light bulb on for 10 hours: 1kWh x $0.12 = $0.12
- a 200W computer on for 10 hours: 2kWh x $0.12 = $0.24
- a 3.75W phone charger on for 10 hours: .0375kWh x $0.12 = $0.0045

I'll assume it takes me 1 hour to write this excuse for a blog. I need to pay for the Internet connection equipment anyway, so writing this blog doesn't change my internet costs - I'll ignore them. All I need is my computer:

65W * 1h = 65Wh
65Wh = .065 kWh
0.65kWh * $0.12/kWh =


Drum roll, please...
This blog is worth a grand total of $0.0078!!!

It also confirms something else very important:
$0.0078 * 12 = $0.10
My blogs are a dime a dozen!
