You're not wrong, it's more than a little ludicrous when you look at the numbers. Infliximab (Remicade) accounts for %10 of Johnson & Johnson's earnings. Does anyone have a full grasp on the scale of J & J? Probably not, peep their wiki page.

Active in 175 countries with $70 billioni earned in 2015. Just one of their drugs is %10 of that, ONE.
Remicade is a great drug but this is absolutely drug company bullshit. They overcharge for it because governments are the ones paying for it. Just like a pack of wood tongue depressors is billed as $150 to a hospital, it's about what they can get away with.
