I recently got out of the military and it's been a complete shock how bad the private healthcare system is. So much red tape, so many charges, so much money being spent on both ends: to the insurance company, again to the insurance company (copays), and then to the provider when the insurance company won't cover things.
With Tricare? "Hey doc, I need this med for my migraines." "Alright, here you go." No charge.
The American health system is a complete scam keeping people under the boot of their employers and of the for-profit insurance companies.
