So I don't believe your assertion.
How can you live with this fear?
Personally speaking, I have no fear of a similar event happening to me. If it happened, I'd figure something out, or die. Generally speaking, "what we think is unbearable proves to be bearable."
The Republican party salutes you, you speak their disgusting and morally bereft "truth" with extreme accuracy.
I tried this, when I lived in the US, even though it was a planned test nobody could give me a quote on what it would cost.
I had great insurance that covered everything. People next to me in the waiting room was paying extra fees to rent the facilities and stuff... Yet, even for a planned procedure neither my doctor or my insurance company would give me a quote or promise that the procedure was covered.
You can't know what the bill will be even for a planned procedure. Even if you ask 3-5 different entities multiple times.
