Public health isn't some privilege that successful societies get to enjoy when every other condition is met, it is the foundational condition that must be met before any society can be successful
The term "social murder" was first introduced by Friedrich Engels in his 1845 work The Condition of the Working-Class in England with regard to the English city of Manchester in the Victorian era. Engels used the term after describing how societal conditions such as poverty, poor housing, and dangerous working conditions have resulted in avoidable excess mortality among the working class.
