Absolutely.
I'll give you a basic example in terms of food costs, food security, and childhood obesity. They're saying that low-income children actually have a higher rate of obesity , because the food that's cheaper to put on the table is often high in calories and high in fat. Fruits and vegetables are simply more expensive. Milk is more expensive than pop. That's one simple example of the health differences in economic classes when it comes to investment.
There is also simple dental care. If you don't have access to a dentist because it costs a lot of money and you don't have coverage, then there's an increased risk of gum disease. The multiplier effect just continues.
