I think you missed my point. The loans were repaid with interest but people like the promoters of the Beatles left the UK for wealth as the system that was put in place made it difficult for individual wealth and I beleive the tax rate would have been more also but would have to see what the comparison was in 1962 or 1963. I know other individuals left for the same reasons. Of course McCartney came back later on. I think the 3rd wealthiest guy in the world is from Mexico.
They may have a good healthcare system I have hear good and bad about it but I do question the price paid monetarily and in opportunities regarding pursuits of ones own desires. It seems the wealthy are being treated like smokers these days.
I think you will find that the top rate of tax is now lower than it was then. I assume, in any case, that you refer to income tax. The State social programmes are not paid for from that tax revenue.
The NHS isn't perfect. How could it be? Private health care isn't prefect either. However, I've seen the NHS develop from its foundation throughout my lifetime in the UK and we wouldn't be without it. I had private health care from time to time, paid for as part of employers' key staff programmes. All you got extra was a nicely appointed private room but the same treatment and the same consultants. It just isn't worth the cost from your own pocket for most individuals.
You can 'pursue your own desires' if you want to pay for private treatment or, as many do, run a private pension scheme in addition to the State scheme. In fact, if your private scheme is acceptable, you can opt out of the State pension scheme.
I don't understand your comment about wealthy people and smokers. If you mean that wealthy people are heavily taxed, then the only truth in that is their higher earnings are taxed at a higher rate. There's nothing unusual about that. Most wealthy people, especially the self-employed, are able to exploit loopholes in the system just as the wealthy in the US do. In the early '60's, the top rate of tax was high and the likes of rock performers hadn't yet learned how to work the tax system in their favour. I think that wealthy people who pay little or no tax are as common in the UK as in the US.
McCartney, Harrison and Starr live (lived in the case of Harrison) in the UK even though they may have other homes abroad. Lennon may have returned if he hadn't been bumped off!
