Americans are much more compliant now, not to mention health and socially conscious. For example, the culture of alcohol use has disparate impacts on black and brown communities: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2771773/ ("African Americans and Hispanics bear a disproportionately greater burden of alcohol-related health problems compared to whites, as evidenced by higher rates of liver cirrhosis, death rates due to cirrhosis, and rates of overall alcohol-related mortality.") That is true even though, for example, black Americans begin drinking later and drink less than white Americans: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3758406/.
