I know a woman who moved from the US to the Netherlands in part because she has severe asthma. There are periods when she cannot work for a month or three, and in the US she'd have trouble keeping her job during those, and then she'd have trouble paying for necessary healthcare. In the Netherlands paying for treatment is a non-issue.

The US economy lost a smart woman with good skills both as a programmer and a project manager because of this. Her contribution to the economy easily outweighs the cost of her health care...
