That's been my survival mechanism. I'd be homeless otherwise but I was able to hyperfixate on work related things and become a workaholic after failing out of school (where I couldn't focus on courses I didn't like).
My life/work balance has never been good, but its awesome to be fixated on the thing people pay you money to do.
Its not OK and we need to nationalize healthcare now. But much of that above graph is also associated with the obesity epedemic and the nutritional collapse (or caloric inflation) of the western diet. Government definitely has a role in that, but its much trickier than obliterating the medical insurance industry (which of course is also tricky).
