First, think about that definition for a moment. What does it mean to "have $1 million"? Do you mean in liquid assets or combined net worth including real estate? Is that a universal number, regardless of where you live, what you earn, and what your expenses are? Does it matter if you earned that $1 million by working for 50 years and putting away a little each year compared to earning $1 million in a year (but spending most of it on wants?)
Second, given that those above, across a very wide spectrum "have $1 million" - how much of that do they then use to pay for health insurance for others, and what is left for them? If you worked very hard for 50 years and scraped together $1 million, and then retired, and then a whole bunch of it was taken away from you and you had to start over, what would you do? How would you feel?
