Here is a fabulous ACLU movie on ordering a pizza in 2010 and the inherent violations of privacy that will be involved. The’ve got the date for the all the medical data far too early though (most stuff will still be on paper then), and actually most of that data use is banned already–unless it’s really for medical uses. Plus there will not be a national healh plan by 2010, even if most lefty ACLU supporters (like me) would favor that! The risk is far greater that employers and their private health plan agents will be "suggesting" that their employees agree to these restrictions (in fact last week one employer added an extra charge for smokers to their health premium)
But you can see where we’re headed without some real safeguards built in, which is why the Health Privacy Project gang are doing such good work. (Even if I diss them from time to time).
