What underlying factor most significantly contributes to the observed disparities in health outcomes among different socioeconomic classes?

One major factor that contributes to differences in health outcomes among various socioeconomic classes is access to healthcare. People in lower socioeconomic classes often face barriers such as lack of health insurance, transportation issues, or living in areas with fewer medical facilities. This means they may not receive regular check-ups or necessary treatments, leading to worse health conditions over time. For example, a person from a low-income neighborhood might ignore symptoms of a chronic illness because they can't afford to see a doctor, resulting in more severe health problems later on. Overall, these barriers can create a cycle where poorer health leads to more financial strain, making it harder for individuals to improve their situation.
