Just saying it's 'semantics' isn't some sort of easy get out. If you didn't mean those things then why write them in the first place, and subsequently why not just say you were wrong?
All you've asked above is would you rather do something you enjoy than something you don't for the same money. This is not what you've said previously, unless you're presuming that being a doctor is equivalent to doing 'dull conveyancing work'.
However, I am pleased to see that you've decided to dip your toe into the ocean of other possible motivations for choosing one type of work rather than another; now can you think further than personal enjoyment as a motivation?
Also you do realise that the putative 95% tax rate was a marginal one, to be levied on earnings over a certain rate, so that rich people wouldn't be taking home 5p in the pound after tax. They would get their tax free allowance (£10,000 reduced as their earnings went over £100,000)), plus 90% of earnings up to £5,000, 80% of earnings between £5001 and £31,785, 60% of earnings between £31,786 and £150,000, 55% of earnings between £150,001 and whatever the new upper limit is....and only on that proportion of their income above that upper limit (say £250,000) would they pay the 95% rate.
Of course all this supposes that there wouldn't be additional steps towards the 95% rate and that the rich wouldn't employ accountants to make sure that their position was as 'efficient' as possible. But don't let any of these facts get in the way of your dishonest defense of the hard working rich who'll be forced to work for 5p in the pound.
