Great video, I would like to make a counter-argument why technology has increased the cost of health care:
The life expectancy of people increased by quite a lot in the last 50 years and a lot of that is due to better drugs, new treatments and better technology. So if a lot of old people used to die to the first serious problem that came with old age their medical costs were relatively low. Today people live for 20 or more years with old age sicknesses which costs lots of money. My grandfather takes several different important drugs each day and was in the hospital for something every 2-3 years in the last decade or two. That wasn't the norm half a century ago.
This is also the case with other medical problems which require more than one treatment or operation to fix. A lot of these became treatable in the last decades and with the higher life expectancy come higher costs.
So it's probably too extreme to just extrapolate from 1900s medical costs to today. Medical and drug licensing increase the price of health care by a lot, but it probably wouldn't decrease by 90% without it. ;)
