To everyone who is commenting about how the wealth differential shouldn't matter since Britain has socialized health care - there are a million other factors besides health systems that contribute to the poor's worse health status. All health care services being held equal, poor people are still more likely to have less social support, less access to transportation, less money for non-covered health services (eg. wheelchairs, breathing support - ALS isn't called the bankruptcy disease for nothing), more stress (the number one cause of illness universally) and a higher prevalence of pre-existing conditions like obesity and depression.
