Shockingly there are many things from 1999 that we'll never get back.
This graph proves that the current administration has failed!
No, it doesn't work that way. Unfortunately the world changes and we have to create new systems to improve from where we are now moving forward. Comparing to 1991 and saying "Look at how much we are failing!" is meaningless.
The healthcare landscape has changed. It is more expensive and the number of people trying to access it is
astronomically higher than it was before. The number of people
without insurance accessing hospital services is also
astronomically higher. The amount of lost revenue from providing services to people who
never pay the bill is astronomically higher.
The graph proves that in spite of the inertia of the current economic subsystem pushing toward fewer insured, more sickness, less access, the ACA was able to help move it in the other direction.
How that is anything but success is beyond comprehension.
