Who can afford a one time medical treatment that costs hundreds of thousands or even millions of dollars?
Almost nobody.
Only the most wealthy in society have the resources to pay for some of these whiz-bang George Jetson futurist cures at millions of dollars per treatment. Private health insurance and government funded Medicare will never cover the cost of these technological marvels.
What has caused this situation?
In a word, Inflation. The US and the Western World in general, are being destroyed by inflation. Inflation is a condition in which the value of currency is reduced, thereby giving the appearance of rising prices. It is NOT healthy for any society to have a period of prolonged inflation, because prices will rise faster than wages and the public will become impoverished. Let's look at the rising cost of living in this country, it has risen exponentially over the past 40 years, but wages have been stagnant. The cost of medical care and education have reached levels that would have been unimaginable thirty years ago. These new medical breakthroughs are following the same trend of rising prices, only in this case the government is actively pushing them along. I think the best explanation was given by the great economist Ludwig Von Mises over sixty years ago, he said
"The great inflations or our age are not acts of God. They are man-made, or to say it bluntly, government made. The are the off shoots of doctrines that ascribe to governments the magic power to create wealth out of nothing and making people happy by raising the national average."
