You people do realize that real, live people work for those insurance companies? I'm one of them. Hundreds of thousands, if not more than a million do. Your opinions basically boil down to "Fuck those people trying to make a living."
The increased prosperity from universal healthcare will open up new jobs. You'd also see folks leave the labor market, as they'd no longer need to work for health insurance and could retire. Also, you'd need new federal healthcare jobs.
