The National health system in the UK offers free health care to all. It's pretty good for emergencies, and used to be good for childbirth, though I hear that is slipping. The real weakness in the system is on-going care or operations for non emergency health issues. As a result, a lot of folks go private - if they can afford it - for operations, as the alternative is a long wait - up to two years in some cases. Several of the private health companies now offer 'opt in' schemes for situations such as this. Most large companies offers workers the option of private health care (at a price), or offer it as a perk. BUPA is the biggest provider - and they are a non-profit, which is what the HMO's should be here IMHO.
The other trend in the UK - as already pointed out - is folks going abroad (Eastern Europe in particular) for operations and, increasingly, dental care!
Having looked at various health care systems around the world, no system will ever satisfy everyone, you just have to find the one that works for the majority. The UK national health system is funded by the taxpayer, which is one of the reasons why gas is now close to $9 a gallon :ack:
