Not so much at the high end (dev/engineer), though. Those $150k US salaries are also going to include generous health plans with little cost to the employee at most employers.
Having long term health problems is highly correlated with not being able to work, though, and losing insurance coverage. This is one of the things that surprises many people who think they're well covered with insurance, and then become ill, and it's one of the most insane things about our system of bundling work and health insurance.
