Assuming that your $150 billion ISS cost is correct, the ISS is 30x
more expensive than Mir, and 15x more expensive than Skylab. *(If ISS
costs are indeed closer to $100 billion, then Mir would be 20x and
Skylab 10x more affordable).

But, is the comparison to the older stations valid? *The ISS is so
much larger and more capable

Of what? Acting as a more comfortable hotel in space for billionaires
and astronauts with nothing to do?
