Over the years, many safeguards have been put in place by the United States Government to reduce its citizens' lead exposure, such as outlawing lead in paints and petrol (Agency for Toxic Substances and Disease Registry, 2017). Despite these safeguards, dangerous levels of lead in the blood are still found in American citizens, and those of low socio-economic status are over-represented (Dewalt et al, 2015).

This creates a positive feedback loop that leads to a lack of upward mobility for low socio-economic populations (Reyes, 2015).
