Finding insurance when you have a pre existing health condition can be difficult. However there are things that you can do to increase your chances of finding a good health insurance policy even if you have been denied in the past.
The health care debate is to a great degree misnamed. It is a debate about sickness care and who has to pay for it. A debate about health care would address the issue that is making our costs skyrocket.
It seems to me that our objectives are to make sure that everyone is as healthy as possible for as long as possible at as low a cost as possible. The first two objectives are, or at least appear to be, at odds with the third. However, a healthier citizenry can in theory be a more productive citizenry. That extra productivity has the potential to make up for the additional cost.
