In that article, it states:
"Alcohol has a greater impact on people from low socio-economic backgrounds, who are more likely to experience its adverse effects compared to people from higher socio-economic backgrounds, even when consuming similar or lower amounts."
Can someone provide some insight here? What does your wage have to do with how you body handles booze?
The human body is pretty able to withstand most injuries, viruses, bacteria and so on. The more stressed a person is the less the body is able to do that recovery. In addition, if and individual is low on the socio-economic scale they might not have available cooping mechanics like resting, taking a day of, or access to social support. A lack of cooping mechanics is also a source for stress, making the body prioritizing other things than recovery.

which says in its abstract: " Individuals with low socioeconomic status (SES) experience disproportionately greater alcohol-attributable health harm than individuals with high SES from similar or lower amounts of alcohol consumption." and "Alcohol use explained up to 27% of the socioeconomic inequalities in mortality. The proportion of socioeconomic inequalities explained systematically differed by drinking pattern, with heavy episodic drinking having a potentially significant explanatory value."
