One of the great benefits of working at a full time job, is that often times your employer will provide health insurance. This insurance doesn't come free, most likely a portion of your salary is deducted to cover it's costs, however becuase you are under a company you can acheive greater discounts through group rates.
Health insurance is simply a type of insurance that will cover the insured person or part when that person or party become sick or injured,etc. The insurer is not always a private organization it can often times be a government agency. There are great differences between health care insurance around the world. For example in Canada health care is part of our social system and is public, where as in the United States health care is for the most part private.
There are several pros and cons to each system, and depending on the area in which you reside you might not have a choice as to which system that you choose. Private health insurance has become one of the most talked about and debated forms of insurance because of the impact that it places on the different levels of society, for example the poor, middle class, and wealthy. Should it be that a person with more money, is allowed to have better medical facilities and attention, and is it not that a services such as health care are a basic human right? I'm not sure if we will ever see an end to this debate, as there is soo many pros and cons to each side, and I'm sure that you can see who would be fighting for which side, and why.
