Earlier quoted context omitted.
I saw Jim Clark (of SGI and Netscape fame) talk one time about his new healthcare startup (Healtheon). He said something insightful that captures a lot of why it's hard to get things done in general: one person's inefficiency is someone else's bottom line.
And someone else's bottom line is also the wages of friends and neighbors. Last I heard healthcare is like the only employment sector that's seeing real growth right now.
Note that this is a Good Thing.
The issue with US (and privatized) healthcare delivery is that there is an incentive (by insurers) to deny treatment, as well as an incentive for healthcare suppliers (hospitals, doctors) to over-deliver treatment, as well as incentives to use more expensive solutions.
Demand in healthcare is inelastic, no one is ever "too healthy".
Supply is always insufficient, so there needs to be a mechanism to resolve that.
In the US, that mechanism is money, or the cost of insurance etc to provide a restriction on demand.
In universal healthcare, that mechanism is a combination of subsidizing medications based on results and waiting lists for limited supplies, prioritized by need (eg surgeries).
