This is a great way to rule out outliers. My home country Australia has 3X the median wealth per adult of the USA. This is similar to the median wealth difference between the USA and China for reference. It shows to be honest having lived in both countries. Specifically it shows in the conditions that minimum wage earners in the USA face, eg. having to live off food stamps as is common for wallmart workers for example is just horrendous. eg. https://www.kiro7.com/news/local/report-amazon-walmart-worke...
Australians usually call out companies that make things in sweatshops where pay is below the poverty line. Specifically clothing in Asia. But i believe we should start doing this for US companies as well. Sure the US minimum wage is higher than say Bangladesh but since the cost of living in the US is higher too so it doesn't change the fact that things manufactured at minimum wage in the US are coming from companies that pay wages below the poverty line.
