Genetic Testing for Potential Employees

Although this is more of an issue in the United States than in Canada because of our different healthcare systems, I think this merited a comment for all the blogaholics. Some employers in the US are trying to gain access to potential employees' genetic information so they can weed out people who will develop incapacitating diseases such as Parkinsons'. This is partly to protect themselves from large health insurance costs. Well, in a country that has no public healthcare system, what do they expect these folks to do if all businesses eventually become able to access this information to remain competitive? The callousness that this implies is outrageous!
