Not trusting corporations is possibly the best advice available. I used to work for the largest insurer on Earth, a "health insurance" company. They quit paying for my insulin, which I need to live. They have enough lawyers they could just pile them physically on my house and suffocate me. They then laid me off due to age. My group of layoffs was 155, and of those 17 were under 40. They did give me a pile of cash not to sue - which I took like the opportunistic bastard I am in the end.
