Once a provider does drop a client as a bad risk, these people, not surprisingly, find it difficult to get new health insurance. Consequently, millions of Americans have no insurance. They live in fear that if they or their kids get ill they will lose everything they have.
When they run out of money they curl up and die.
How is a system allowed to exist where private health providers get away with such a colossal crime against humanity? No other Western country would put up with it.
These corporations provide millions in funds to politicians to stop any reform. That's why, even when the Democrats had the majority in both Houses of Congress, when Barack Obama was elected President, his own supporters wouldn't consider an option where people could choose a government-run scheme. There were more than enough politicians in the insurers' pockets to maintain the moneymaking racket.
And what's the crime about Obamacare that their highest court threatened to overturn it this week? Opponents are apparently outraged that under Obamacare most Americans are required to get subsidised health coverage that includes their children.
In turn, providers can't refuse applicants with pre-existing medical problems and, while employers are subsidised, they must provide coverage for their employees.
The drug companies are levied to help pay for it and, to appease the right-wing, the whole health system remains in private hands and requires no additional taxes. They expected the conservatives to be grateful.
Obamacare is a step in the correct direction but it is so right-wing that even the Act Party in this country would blush.
So why have the providers been able to whip up so much support to where an overwhelming majority of the country oppose Obamacare?
Apart from the usual lies and misinformation, it comes down to this simple equation: the wealthy and healthy half of America receives the finest private health care in the world at an affordable price. They get it because their sick and poor neighbours are cut out.
It's a classic "screw you", a deformed Darwinism where the market rules and the fittest survive.
New Zealand owes a lot of thanks to the early socialists who set up our public health system. All citizens paid according to their means and provided the means so everyone received the health care they needed.
Although our wealthy can pay a private provider for extra benefits, we should be proud that every New Zealander takes for granted our first-world healthcare. How civilised not to have a completely privatised health system.
In any event, Prime Minister John Key and his party would have to sell the power and water companies, the rail, Air New Zealand and Kiwibank before they even considered moving on health.
Hey, wait a minute ...
