More and more, the United States is becoming polarized: there is the healthy wealthier class and there are the unhealthy poor.
Poorer, less-educated populations are less likely to have access to quality health care. They are more likely to smoke, lack proper nutrition and tend not to get enough exercise. They are more likely to live in overcrowded conditions and be exposed to pollution and toxins in their environment. They have more stress and less control over their lives.
Being poor increases the likelihood of suffering from preventable diseases such as diabetes and heart disease, and lowers your life expectancy.
