You know that there are studies addressing this, right? I didn't just make it up.
Here's an overview study that reviewed other studies: https://jphe.amegroups.org/article/view/9493/html
"Pre-COVID-19 interviews with a high-income vaccine hesitant sample in Perth, Australia found that vaccine hesitancy was based on an inflated sense of agency in making medical decisions without doctors or public health officials, and a preference for “natural” methods of healthcare (30)."
"A similar study in the United States reported on interviews from 25 White mothers in a wealthy community who refused vaccination for their children (31). These participants reported high levels of perceived personal efficacy in making health decisions for their children and higher confidence in preventing illness through individual “natural” measures such as eating organic food and exercising. Additionally, these participants report lower perceived risk of infection or disease, which is contrasted with their high perceived risk of vaccination."
"Vaccine hesitancy among those with privilege may be more than just a product of resource access. There is evidence that individuals with high socioeconomic status perceive themselves to be more capable, hardworking, important, and deserving of resources and privileges than others (32,33)"
