Meanwhile, the presence of lead in gasoline and paint back then, might be the actual reason for 80% of what's wrong right now.

Many of the lawmakers and elected officials grew up in environments that had that lead exposure

The lead–crime hypothesis proposes that the sharp decline in crime rates in the industrialised world in the 1990s and beyond, after decades of increased crime, can be attributed to the reduction of lead poisoning. Lead is widely understood to be toxic to multiple organs of the human body, particularly the human brain. Concerns about even low levels of exposure began in the 1970s; in the decades since, scientists have concluded that no safe threshold for lead exposure exists.[1][2] The major source of lead exposure during the 20th century was leaded gasoline. The hypothesis argues that the removal of lead additives from motor fuel, and the consequent decline in children's lead exposure, explains the fall in crime rates in the United States beginning in the 1990s.[3] This hypothesis also offers an explanation of the rise in crime in the preceding decades as the result of increased lead exposure throughout the mid-20th century.[4] Other explanations have been proposed, including situational crime prevention and interactions between many other factors with complex, multifactorial causation.[5]
