I am very sorry to hear about your circumstances. Like you said, it is far too common.
This is why we need universal healthcare. It is inexcusable that we still live in this profit-driven system while all other developed countries have universal care, including Mexico.
There are many reasons for it. The greed runs deep. I wrote a 3 part series on why universal healthcare is the best system. This is more than the same regurgitated tropes but a strong analysis of exactly why, in layman’s terms. Since you are running for office, maybe you will find some valuable information to consider in the series. Not an extremely long read. Here is the first of the 3. The other 2 are on my site. https://issuesunite.com/how-universal-healthcare-is-the-best-system-pt-i/
