US is not the place for permanent settlement

I became a permanent resident in US a few months back. Now I’m skeptical living here permanently due to many reasons: 1. Healthcare: I’m suffering from chronicle diseases (diabetes, high blood pressure). The moment I quit/lose my job, I will not be able to afford medical service costs. I recently had very bad experiences with getting medical assistance from primary care when I suffered from abdominal pain, chest pain etc. Primary care team does not respond hence only option was to go to urgent care which is too expensive. 2. Affordable homes: There is a totally weird competition for home purchasing in Seattle/east/north. Unreasonable selling prices and low rated schools everywhere. 3. Not living closer to parents in their last days Parents are getting older and living far from them (the other side of the world) make me guilty every week. 4. I do not experience drastic difference of education level in kids in my home country and US Thinking about save money as much as possible and get ready to leave anytime. With 300k savings, I can comfortably retire in my home country where healthcare is free. I’m writing this here to discuss with fellow blind community to understand if my thinking are justifiable/reasonable.
