You're "making good money in Silicon Valley" and don't have health insurance? Are you freelancing and choosing not to purchase insurance?
In the US, they have this concept of a "pre-existing condition", and depending on your situation, a health insurance might cover it, or not, as far as I understand.
Even making good money in SV, you can still end up with a medical bankruptcy (or your family, for that matter).
Just like I won't expound on German healthcare policy, maybe you should reserve judgement on US healthcare policy until you actually know what you're talking about.
