Nice to see a debate where passions run high, but consider the following (figures are for illustration only - I appreciate simply adding them up is not entirely valid)1) No one who has ever worked for an insurance company would ever argue they are a model of efficiency – lets be generous and say they only waste 10% of their resources.2) Insurance companies are corporate bodies – in the UK that means paying 20% of profit in corporate tax. 3) Insurance companies are owned by shareholders (or similar) and need to make a return on investment – lets say a lowly 5%.4) Insurance companies have loss making years and therefore have to retain earnings from profitable years to cover financial liabilities – lets say a paltry 3%.5) Insurance companies are FSA regulated and need to spend a huge amount every year on FSA compliance relating to sales of regulated products and investment disclosure – lets assume 1%Total leakage away from medical expenditure if private insurance companies were to replace the NHS as a source of funding, could easily be 20% to 40%.Hmmm. Not quite so clear cut is it……All this ignores the fact that even if insurers replaced the NHS as funders, there would still need to be an organisation to manage the central infrastructure, just like the railways. You can deregulate the carriers, but you still need Railtrack, because you can’t have competing tracks. All this achieves is a transfer of inefficiency away from the privatised elements, consolidating it in the owner of the non-profit making infrastructure elements. It moves the problems, it doesn’t alleviate them.I'm pretty supportive of capitalism as an economic and democratic philosophy, but for those who eschew it to the degree of zero taxes, there is an easy way to practice what you preach - simply move to any one of the countries where there are no income taxes - Nevis, Andorra, Nauru, Sark, Monaco, etc.Of course you may find either NO infrastructure Nevis, Nauru), or one that is paid for by incredibly high property values and beer at £12 a pint (Sark, Monaco), so you might find life no less expensive. Thats the world free market for you...
