michael moore isn't exactly unbiased, but the anecdote here isn't fabricated. the insurance company uses a loophole it created to deny this guy coverage, which effectively would have killed him. of course, bad publicity is more damaging to this company's profits than just paying for his operation, so that's what they did.
how many guys like this didn't have the same luck?
yes, that's why people with pre-existing medical conditions cannot receive affordable health insurance, and that's why there are draconian screenings of any applicant to an insurer. just a personal anecdote here - i had to tell a health insurance company whether or not i participated in drag races in the last 6 years. this is a ridiculous invasion of privacy - what i do in my own time is my ing business, not something for an insurance company to use as part of their formula to determine how much money i'd have to pay them so they can earn profit from me.
for-profit health insurance is inhuman, and judging by how much you suck their you must work for one.
