What is your "it"?
If we assume all 2,000 people that use daraprim daily at $120 a daily dose, it comes out to $87,600,000 yearly.
If we assume half of Americans don't have insurance (160 million), each American would see a hefty 50 cent increase in their yearly premiums.
This is a gross simplification, but $100,000,000 is a literal drop in the bucket.
These are small fish and focusing on them lets the big players make even more moves.
